I had started to work on a window manager sort of thing that would handle the display while other apps would send it "windows" (rectangles) to put on the screen. The window manager would also
have to intercept some buttons or something to allow you to switch between apps.

It sounds like the empeg guys are going to something like this soon, so I abandoned my project (for now, anyways). I was stuck trying to figure out a way to fake the main player grabbing the display. Maybe using a "phantom device" like the IR remote hack someone did a while back...
