+1 on the wireless capability -- perhaps this could be done via a TinkerKit attachable?
@Vrmithrax: What do you mean by severe I/O limitations? It does appear to have several pin outs -- just not in the Arduino shield format
I just mean that it's more of a limited proposition than a standard Arduino. The I/O is kind of there, but it's all tied up in the built-in functions (buttons, joysticks, etc), other than the few available for use with Tinkerkits. With a regular Arduino system, you have much more I/O options, plus the shield expansion capabilities. That's what I mean by severe I/O limitations...
