A friend of mine, Bob Huott, has worked extensively with tactex.  He is  
basically abandoning it because of its limitations.  It does do  
multi-touch very well, but it has a low refresh rate, and you need  
roughly 2cm between touches in order for them to be detected as  
individual events rather than one.  Also, it takes a decent amount of  
pressure to actuate it, but it is pressure sensitive as well.

As for building a Lemur with Pd and a tablet, there is another  
limitation in that most OS's only support one pointer, so even if the  
screen could handle multi-touch, the OS probably could not.  But it  
would be cool...
