It took too much fiddling last night, and I still have more fiddling to do tonight, but I did manage to get (free)DOS installed in qemu.
Now I just have to figure out how to pass it a : so that I can change drives and install software. (The colon is under a layer of shortcuts by default, and army is ignoring my attempts to use it.)
@ajroach42 I was thinking with the radio transmitter in the stylus, angle & pressure sensitive, etc, while still being able to have a capacitive touchscreen for multitouch. Relative pointing is definitely better for using a touchscreen for things that aren't designed for capacitive touchscreens, but then you're covering part of the screen with your finger for no good reason :)
