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...
