do you guys have a plan as far as supporting
3-button mice? as far as I know, there are
only 2 options for 3 button MICE(logitech, mouse systems or something)
and several for "3 button" trackballs
(in quotes because usually the middle button is very awkward)
such as logitech and mouse systems, plus various cheesy ones
(microtrac trackball for example)

each probably has a different way of simulating 
a mouse click; will figuring out the signals be difficult?

there are also several new 2 button mice, which
seem like a waste for X...
