Frankly, I do not know if they are free. But as nobody pays me to play 
with QEmu, I do not care about Windows so much. And the Wacom drivers for 
Linux are free.

BTW I prefer a virtual wacom tablet to Summagraphics, since kudzu (the 
hardware detection which is used in Knoppix) can detect it. Unfortunately 
just the USB version :-(

Wow! What an offer! I have some documentation somewhere, I just had a 
look, and only found the Summagraphics documentation. I will look harder.

My favourite cartoonist, Jamiri, is very proud of his Wacom tablet. IIRC, 
it has an integrated LCD display. So, I assume absolute positioning is 
automatically switched on with that tablet.

Thank you!
