I was wondering if the situation has changed in SDL with regards to touchon W7:
http://www.libsdl.org/tmp/SDL/README.touch
I am currently lined up to add support for multitouch into Blender for
Google Summer of Code, and based on the development interest in SDL I was
hoping I might be able to implement touch through it.
I can test for Wacom (Atmel) and possibly N-trig multitouch devices, for
both Windows 7 and Linux if given instructions.
