iChatUSBCam is a haxie which allows you to use USB webcams to video-conference in iChat AV. Until this haxie was made available you could only use FireWire cameras, such as Apple's iSight to video conference, and now with the release of iChat AV 2.1 (Beta), you can also video conference with Windows-based friends using AIM 5.5. iChatUSBCam requires Unsanity's ApplicationEnhancer.
