Nike sneakers communicate wirelessly with iPod Nanos

The Nike+ running shoes contain a pedometer accelerometer sensor and a wireless transmitter that talks to a receiver you plug into your iPod Nano. You program your workout routine (and music) into your Nano, and it collaborates with the sensor to deliver messages like "two miles to go" to your headphones as you go, and tracks your workout for upload to your PC's fitness-tracking app. I'm no runner, but I'm fascinated to see what the hardware hackers make of a wireless sensor that connects to the most popular portable player on the market.
