That's a good idea; it wouldn't require cell service and I do have a nice collection of phones with cracked screens. Thanks rrlev.

Still, it would be nice if you could just select USB and hit it play. I'm hitting the point in retirement where I need a hobby, and I think I saw that the N2/N3 are Raspberry Pi based; so I may start poking around. I'm going to review the early threads, but if anyone has a good starting point for cracking open the N2/N3 code base, please send up a flare.
