If you have any more questions feel free to ask me.

This is all well and good, something I am really interested in actually buying (I never buy apps for my itouch), but I have a few questions:
1. If it connects via wifi, what, if anything would have to be done to the gaming adapter on the robot?
2. For joysticks, does the app have virtual joystics on screen, or does it use the accelerometer in the device?
3. How would a user go about changing user I/O? I personally think this needs to be easily accessible at all times.
