I need to get an interactive whiteboard working with NetBSD. It uses USB  
and the company that
produces them supply some Linux source code. They are based in Didcot in  
Oxfordshire. I'm
hoping to get a loan unit, but otherwise it would mean a trip to their  
offices. When finished
the board should be seen as a mouse. I think there will be two components  
to this work. The
first is the driver part (IIRC when I tried it, it got some of the way  
there with NetBSD 1.6
out of the box). The second part will be a userland utility to calibrate  
the device and a
small X program to allow the calibration to take place (e.g. touch cross  
at top-left, at
bottom-right and then random point in middle). A further enhancement would  
be an X window
with a couple of buttons in allowing you to emulate right mouse clicks.

If you are interested, please contact me at sborrill AT precedence.co.uk
