Ok, I've got a really stupid question. Since the wifi chip on the N810 is nothing more than a controller for the transmitter and receiver, and all of the signal control and whatnot is done by the firmware (or at least that's how I understand it), how hard would it be to write a firmware that allows you to temporarily re-purpose the wifi on the N810 to be an FM radio receiver? I don't know for certain if this is possible, but I thought I'd ask just in case. If it is possible, it'd be awesome if someone were to actually write a program that could do that. Sure, you'd loose your wifi while it was being used for fm radio, but hey, that's a small price to pay to get fm radio capabilities on the N810.

(assuming of course it's even possible)
