Even if you could convince Martin to do a WinCE compilation of Orbiter core, what do you expect to see on a PocketPC?
The amount of Windows Mobile devices with any significant 3D graphics capability is vanishingly small.
Are you kidding? I have a 3D racing game for my iPaq 2210 (Which was made in 2003, 400MHz processor)... It looked a bit like PS1 graphics, but it still ran pretty well. I doubt rendering a couple textured spheres on screen and a (low-poly) model of the Orbiter would be too much. Of course, it would all have to be done on the CPU because I don't think any of them have dedicated graphics processors. I think the bigger problem would be what tblaxland mentioned with the screen size and situational awareness, and of course, all the math calculations going on behind the scenes. I think the 3D part wouldn't be the hard part.
Although, get one of those super-expensive MicroPCs and I'm sure they can run Orbiter out of the box
P.S. PocketPCs would probably have 3D processors by now if cell phones and smart phones and blackbarries (etc) didn't takeover by storm like they have, PocketPCs were increasing in power every day but a lot of interest was lost on them over the years, not as many people are writing new software for it. I would still love Command & Conquer for the PocketPC though (Source code would be handy, of course!) :speakcool:
