Pico-ITX IA32 is way overkill for this application. What those of us with home servers probably want is more like the Displaylink stuff, where it's not much more than a wifi-attached framebuffer and the smarts are on the PC. Not that that would suit Andy's parents, but even they would be better off with some little ARM board. Some of the commercial photo frames probably have Sigmatel chips in, but they're done by Sigmatel Waltham (i.e. not Cambridge or Austin) and I've no idea what the software is like.
