Wuala is a new company with a compelling story for Web users: If you want to share files--music, videos, anything--with your friends and family, it will let you do it for free, with no file-size or bandwidth limits.

The catch: You get 1GB of storage for free. Beyond that, you get access to free storage in proportion to the amount of storage from your own hard drive that you share with the Wuala community.

You add files to your Wuala drive by dragging them into the app.

Wuala uses a "mesh" of hard drives from all its users. Everything you share gets sliced into 500 or so pieces and the distributed in tiny bits, and redundancy, to thousands of other users. When you, or someone you're sharing the file with, wants to load or play a file, it's pulled in from users, BitTorrent-like.

It's not easy to build a reliable storage network based on end-user PCs, which tend to be online only sporadically, and with poor upstream bandwidth. Wuala rewards its users that stay online: The amount of storage users have access to is equal to the amount of storage from their own drives that they've set aside for the Wuala network, multiplied by the average percentage of time that their machine is online. In other words, if you're sharing 20GB of your hard disk, and your PC is on 50 percent of the time, you'll be able to use 10GB of space on the Wuala network. PCs that are network-connected less than 20 percent of the time cannot share their space at all.

All files you put up on the network are replicated extensively, so you'll always be able to get the data that you've uploaded. CEO Dominik Grolimund assured me. We had a nice talk about the mechanics of his network's security, redundancy, and reliability that I won't replay here, other than to say that if Wuala doesn't work as reliably as traditional centralized storage, it's going to be a very short-lived start-up.

Peer-to-peer company BitTorrent is set to announce on Tuesday morning the availability of a new enterprise content delivery product, BitTorrent DNA. Designed for companies that use streaming video, large downloads or games over the Web, the launch of BitTorrent DNA marks yet another conscious move by the San Francisco-based software brand to move beyond its roots as the creator of file-sharing protocol that became nearly synonymous with digital piracy over the past few years.

BitTorrent described the new BitTorrent DNA product in a statement as "the ideal solution for publishers seeking ways to overcome the obstacles associated with centralized content delivery, such as slow downloads, choppy video streams, and inefficient use of network infrastructure." The inaugural client for the new content delivery network (CDN) is online video start-up Brightcove, which powers a number of large companies' broadband media operations.

BitTorrent DNA will be used to "accelerate" the delivery of the video hosted on Brightcove's platform.

With the rise of online video and large-scale media downloads, content delivery has become a crowded niche in the market. BitTorrent DNA will square off with industry leaders like Akamai Technologies--the force behind CBS' video distribution network as well as a host of others. BitTorrent is hoping, however, that its massive following (150 million downloads of its client, according to the company) will help give it an edge.

In addition, the peer-to-peer format has become increasingly popular in the streaming video space, with recent entries like Joost and Babelgum touting P2P technology as the backbone for their professional-quality video content.

In February, BitTorrent announced that it was creating a digital download store that would use that robust user base as a way to legally transfer large movies, games and other files. The company has also forged alliances with major movie studios for legal film downloads.

Meanwhile, the exhaustive battle over online piracy wages on.
