From Tommy Kammerer:
This is the free version of jfControl including 3 layouts from the full version.
With this app you are able to remotely control your computer from anywhere in your apartment. (Wi-Fi required)
Switch it off from the bedroom, turn up the volume from the kitchen, control a full keynote presentation or just start a video sitting on the couch in front of your mac mini that is connected to your HDTV.
No hassling around with IP addresses, nothing to config, it just works. Thank you bonjour.
This remote control does only work with OS X 10.4 or higher. You need a Mac, Windows is not supported.
You have to install a free application on your mac. Download it from http://www.digitalsirup.com/jfcontrol
If the remote does not work, chances are something (i.e. firewall) is blocking the traffic. Contact me and we will figure this out. (I'm not able to respond to reviews)
In this lite version you can control iTunes, finder or shutdown computers in your network. The full version includes many different layouts to control eyeTV, frontrow, plex, safari, keynote, quicktime, dvd player, numpad, mouse and more!
