i haven't said anything about performance. but the possibility to do that.

the only thing a found about qemu and n800 is that n800 runs under qemu in pc. so i dunno.

i do not own a n800 myself. i'm just planing to buy one

also a happy thing would be to run arm pocketpc apps on n800 with wine or something...
