UPDATE: With the release of the Android ADK for use with Arduino, this project got a whole lot more feasible for a lot less hacking and costing monies. So I'm probably going to go in that direction.

One more thing, what would any of you guys recommend for a force feedback output on handle bars that could hook into an Arduino board? I'm looking for a similar effect to a rumble pak, and rather not use an audio cue, as users would be listening for that, rather than cars and stuff. Any ideas?
