Anyone ever give any thought to turning a RioCar into a Rio Receiver? I've got a spare 10gig RioCar, but I'd like it to pull all it's music from the network (permanent installation in home) like the RioReciever ... Has much thought ever gone into something like this?

You could do this with enough kernel hackery. Build and flash a NFS-root kernel and suborn the mount syscall to mount NFS volumes for /drive0 and /drive1 partitions too. I'm now slightly kicking myself for not buying a stack of £140 car-players and turning them into receivers: same price, quite considerably better screen.

Alternatively, get together with the guy who's rewritten the Rio Receiver client from scratch, plus the guy who's written the framebuffer layer for the car-player. Retargetting, or even rewriting, the Rio Receiver client is a lot simpler than implementing the whole car player with all its caching, mute and battery sense, etc.
