Ok but it should be possible to say "intercept" the event of a tap, double tap, drap with appropriate coordinates and do something usefull with them. I'm thinking of something like logitech wheel mouse drivers for OS X. I know they use USB which is fairly more simple than low level firmware stuff but eh! i'm just beginning my investigation;)
