So I bought a clunker G3 iBook and wanted to  make it a touch screen unit.  I called the people at Troll Touch Screens and go a very unsatisfactory we will not sell you the parts, unless we do it here at the factory. Thumbs down for them. especially at $649

So I searched elswhere and saw a couple items, but particularly this on one ebay that looked attractive:

But I am curious where I could find a driver for it
or somehow make OS X belive its the track pad.

Any ideas?
