Very cool.

* Are there non-table uses (such as registering facial features, as 
opposed to opentouch fingers-on-a-table stuff)? I couldn't find demo 
pics/movies of any.

* Do I understand correctly that:

   + Tuio for Squeak and the pre-requisite OSC are MIT license.

   + Any application will require that the user separately have the 
reacTIVision framework installed, which is GPL (not LGPL). Being 
separately installable, it should be sufficiently "arms length" to use 
with non GPL licenses.

   + No other parts to worry about?
