I'm attempting to pair and use my PS3 bluetooth joypads with my n800. They work great on my linux laptop and are very portable. Compiling the pairing app and performing the USB based sync is the first step. I would have to see what is available to create the /dev/input/js0 devices next. But I think this would be the best game interface for the lack of cables makes it easy to have more than one player without the use of hubs.
