I had, at one time, set up the Wiimote to control my Nokia remotely. I mapped out the buttons so that could pretty much do everything with it, too. Something like that without the mess of vomiting a tar file all over my root directory would be nice as a start.

If a dedicated dpad with controls was made just for the Nokia and it was supported properly, it would be absolutely perfect. Especially nice if it was small and convenient so that I can just tuck away the N800 in a large pocket somewhere like, say, in my backpack and then just keep a teeny remote in my front pocket. This would be great for wired headphones.

...wired! But wait! What about us bluetooth headphone people? Don't most of these headphones ALREADY have a few controls? Aren't they already RIGHT THERE on my oversized, meaty human head? How about the OS just sorta SUPPORT them so that app writers can USE them?
