Fantastic stuff!

There's also the NUI group [1] and David Wallin [2] working on multitouch
UIs. David Wallin, in particular, works on touchlib [3], a TUIO-based
multitouch library. touchlib will (AFAIK) be adding fiducial support as well
[4].

Simon, with your TUIO client - does this mean that one could use other
libraries (say, touchlib) to send data to Tuio for Squeak?

Since touchlib's licence is the New BSD Licence, this might address Howard
Stearns' licence concerns.
