such a project should look at providing multitouch independent of hardware
support. so writing a driver is probably included to test the code, but how
the actual hardware works (video camera or resistive or ...) doesn't matter.

no, there is no API. that's the tricky bit.

I've got a proposal for MT support by Ashish Kumar Rai in front of me and I
guess we'll beat it into shape until it's realizable. I don't know if GSoC
supports collaborative projects, but that might be worth investigating if you
want to work on this.

There are no howtos on XI2 yet because it's still in motion.
