It's a 1024x768 camera with a 100hz refresh rate that passes you the x & y coordinates for up to 4 points. It's will hands-down outperform a USB webcam, unless you spend hundreds of dollars on it and much effort steamlining everything. As far as performance and ease, the Wii Remote is much more advanced. If you're just doing it for the experience, go ahead, but I suspect you'll spend a large amount of your time on the capture step and very little on the head tracking.
