Use an Android tablet as a Wacom drawing tablet for a PC? Since a nice Wacom tablet is a bit pricey, especially for someone like me who doesn't do much graphic editing, I was wondering if it is possible to use a tablet (i.e. my Nexus 7) as a Wacom-esque drawing tablet when connected to a Linux computer?

I did a bit of searching, however most of the info I found is for using a Wacom tablet on an Android device. I've never used a Wacom device, however I have been doing some graphic editing in Gimp, and think it would be much easier than just using a mouse. And since I have a Nexus 7, it seemed like the logical place to start. I would have to use the Nexus as a USB peripheral for the computer, and I don't know if it is possible to transmit the touch screen coordinates to the PC.

If anyone can point me in the right direction, I'd appreciate it!
The GfxTablet project should allow you to do this.  It's network-based rather than USB though.
