For Google Summer of Code this summer my lab (http://ecologylab.net
) developed an open source TUIO hid bridge driver for windows. It's purpose is very similar to that of multi-touch vista, but we believe it performs better and is a bit cleaner. We also support 5 simultaneous TUIO sensors on multiple monitors.
If anyone would be interested in checking it out we have it hosted on github at: https://github.com/ecologylab/EcoTUIODriver
People trying it out and feedback would be much appreciated.
