I am sorry I misunderstood, so you are not looking for an app you're looking to create an app? I am not sure what else I would like to use it for. We really only use it to allow my granddaughter the chance to watch cartoons since we have neither TV reception or cable.
Latency is hellish over wireless G (i can't help that, budget tablet only supports that) But I think I''ll make a turn based game for it. Phone/tablet is controller.
