Thanks, looking at synergy atm. The "not directly connected" argument is 
not very persuading to me - IP or USB - not a big difference? In the end, 
I could connect a PDA over USB too - just like a normal tablet... And just 
moving the mouse is not enough - a tablet does more. And I want to use 
gimp's capabilities that exceed that what a mouse can deliver. One could 
write a plugin to Gimp, I assume, but I'd prefer to make it system-wide 
accessible.

Thanks
