Curious how the Apple/Nike+ iPod accessory set works, the hackers over at SparkFun have taken apart both the shoe insert and the iPod receiver. You can check out all the details here, including some discussion of the hardware choices Apple made.
Interestingly, the shoe insert is transmit-only, whereas the little white gadget that plugs into the iPod’s dock connector has a chip capable of both reception and transmission. With the right hacking, it might be possible to get iPods to talk to each other over a short range – surely not fast enough to transfer music, but “now playing” info is within the realm of possibility.
