One thing which occured to me after fiddling around with Quake 2 on the N800 is that the port of quetoo currently only uses software rendering. The N800 has a PowerVR MBX 3d accelerator, which has seen pretty much zero use thus far. This same accelerator is playing Quake 3 on the latest Dell Axim at 640*480 at 25 fps. Granted, the Axim has about twice the clockspeed of the n800, but a Quake 2 or Quake 1 acceleration would be much less taxing than Quake 3, as well. Any crafty programmers with too much time on their hands intrigued by the possibilities?
