The characteristically frenetic Consumer Electronics Show may have slowed its pace in response to tech's economic dip, but there are still a few stunners claiming the spotlight at the Vegas show. And some of them aren't even gadgets.

Meet some of the software on the show floor.

Palm's new WebOS passed its first test: it looks good. But will the device attract legions of developers?

Just hours after Palm showed off its new operating system running on the Palm Pre, details are still rolling in about the unit and its software. One important factor that will have to be addressed is application development and distribution. Palm has confirmed plans to administer some sort of central store for application downloads. But there still is scarce information about how that will actually work.

Palm's Stephane Maes said that Palm will not attempt to approve every single application developed for WebOS, as Apple does for iPhone applications.

"Certainly, we want to let a thousand flowers bloom," he said. "Every now and then there are a few dandelions we'll want to winnow out."

Unable to let the clichéd misquote of Mao Zedong pass (he actually persecuted many of those who dared let their ideas bloom), let's move on to ask the more important questions that went unanswered this morning.

If Palm is retaining some right to refuse applications, how will those choices be made? Apple has faced its fair share of criticism over nebulous policies for approving or rejecting applications for the App Store, which have frustrated many developers even as they've flocked to the App Store.

Even if Palm takes a laissez-faire approach to the types of applications created for WebOS, will the Palm Store be the exclusive venue for those applications, or will Palm allow competition between the types of online stores that sell current Palm OS applications and its own?

How will the WebOS SDK work? The Mojo SDK is available as a private prerelease, according to a message posted by Palm on its developer home page, and will be a public download later in the year.

Developers will use Mojo, WebOS's application framework, to develop WebOS applications using standard technologies such as HTML5, CSS, and JavaScript. That means it will likely be much easier for application developers to get up and running on WebOS as compared to the time needed to learn platforms such as Android, the iPhone, or BlackBerry. Palm also says there will be a way to migrate older Palm OS applications to WebOS, but doesn't say how that will work or how it might affect performance.

Palm, a mobile computing pioneer, is well-versed in running a development organization but times have changed since the Palm OS was the PDA world's dominant operating system. It is unclear whether the company will be able to reclaim developers who have moved onto the iPhone, BlackBerry, Windows Mobile, or Android.

These are crucial questions to consider in judging how WebOS and the Palm Pre will play in the current market, not the least being that developer support is a key factor in making a smartphone a more attractive product. At least one Palm developer contacted us urging Palm to resolve these issues sooner rather than later.

Bill MacAdam, director of product development at auto industry software developer GigglePop and longtime Palm OS developer, wants very much to known what Palm has in mind regarding application distribution.

"We very much need to maintain the existing distribution model where the installation of software can take place without going through a store," he wrote in an e-mail. "While a store is a convenient place for consumers to purchase applications, it doesn't work well for business / enterprise applications. It is also very important that we have a very specific roadmap to help us with the transition."

Palm's a little late to the Smartphone 2.0 game, but it got off to a good start with the Palm Pre roll out. Obviously, it will take much more than a flashy demo to get Palm back on track. How the company handles application development will loom large in its success or failure.

LimeWire 5.0 allows users to share files with friends on any Jabber-compatible system, as well as to have search results incorporate files from the LimeWire store.

LAS VEGAS--Get ready for the collision of social networking and peer-to-peer file sharing.

With the beta release of LimeWire 5.0 (download for Windows| Mac), which was announced at the Consumer Electronics Show here, the popular P2P service is incorporating a social element that will enable people using Jabber-compatible services like Gmail to share files with friends on their buddy lists. Lime Wire calls this a "personal sharing network."

The idea, said Lime Wire CEO George Searle, is to add trusted context to user searches for content, given that people are more likely to want--and feel comfortable with--content from people they know.

Additionally, Searle explained that the new social features of LimeWire--which has 70 million monthly unique users and more than 5 billion queries a month--will enable people to choose whether to make files available to the public at large, or just to their friends and family.

In many ways, this is much like many other content-sharing systems. But to Searle, adding a social component to LimeWire means making what is already an extremely popular service more personal to many users.

Essentially, the way the new feature works is that users will be able to decide whether to make files--photographs, for example--available to anyone on LimeWire, or just to people on their buddy lists. Similarly, users will be able to search for files from their friends. And this will take advantage of a sharing system that tens of millions of people already use, something that Lime Wire hopes will encourage many on the service to adopt the social elements.

Searle said he hopes that the social feature will allow users to trust the sources of the content they share across the system in a way that's not really possible when sharing with strangers.

With the new year under way and the holidays on the back burner, CNET's first big coverage extravaganza of 2008 was CES. The annual Consumer Electronics Show, which runs through the end of this week, was predictably brimming with cool gadgets and new technology. Many of our editors were on hand to give their take on all the sleek new products. Check out our extensive coverage of CES here. Though I was jealous to see all of the cool new items coming out of Las Vegas while I remained in San Francisco, I knew the next week would be the Mac users' turn.

In only a few days, the Macworld expo will once again descend upon San Francisco's Moscone Center, and Steve Jobs will take the stage to announce the latest Apple products. With last years release of the iPhone, this year is sure to be closely watched for the next big thing from Apple. Our very own Tom Krazit's One More Thing blog will have updates on new products, and we're going to have a CNET Macworld landing page (still in the works) for all the latest news from the show floor. One of our editors, Daniel Terdiman, was so excited, he was actually inspired to write some Macworld haiku.

So what's in store for this year's keynote? The speculation has reached a feverish pitch around Mac rumor sites with some people saying we're going to see new slimmer Mac laptops, while others are sure something else even bigger will be released. To add to the excitement (and maybe to remind CES attendees that theirs isn't the only conference in January), Apple released new Mac Pro desktops this week in advance of Macworld. Some rumor sites speculate the early release means Apple has enough great stuff to announce at the keynote that they can afford to let out some big news early. We'll just have to wait and see, but you can bet I'm excited to find out! Make sure to check this space next Tuesday for a breakdown of the new hardware and software releases from the keynote speech.

In other Macworld news, I will be joining the VersionTracker team in booth 4810 in the West Hall, so if you're at Macworld, drop by and say hello! We'll have all the latest news about VersionTracker, MacFixIt, and iPhone Atlas, and we'll have a great show special for new and renewing VersionTracker Pro customers.
