i did some cursory digging, but i don't really want to read the A2DP or AVRCP specifications to see how much data is allowed in the non-audio payload. Besides, PAN exists, but i imagine you have to do something on your phone to allow it.

Most of these expensive things also have wifi, though, don't they?
