About 1.5 years ago did a college project with one of these things. Is the Quanta touchpanel an optical one? Are there lenses in each of the top corners? If so, we had a similar screen. We had to get it to work with Linux, which back then was a tough due to kernel not quite having driver support (believe it's included since kernel 2.8.32, partially in .31) It's not true multitouch because somewhere halfway the infrared cameras can get confused, so you can't really use more than two points, though sometimes you can use 4. Benefits are however that you don't have to actually touch the screen but can hover slightly over it. For the project we deployed a location tracking system on it, using a custom Open Street Maps OpenGL app with markers, manipulated using the multitouch.
