Here's a clever idea. As USA Today reports: "The wireless kit lets Nike's new Air Zoom Moire shoes send fitness data to your iPod Nano -- via a sensor you tuck inside the running shoe and a small receiver that attaches to the Nano. As you run, the sensor records your distance, time, pace and calories burned in real time and displays data on the Nano. At the push of a button, audio feedback is delivered through Nano's earbuds."
It's on Apple's site.
However, The Apple Core blog adds: "Conspiracy theorists hoping that the iPod dongle was a forbearer to a wider Bluetooth announcement will be disappointed to learn that the Nike+ iPod transponder uses a proprietary 2.4 GHz signal to transfer information to the iPod. This means that third party manufacturers won't be making wireless accessories (i.e. headphones) for Nike+ any time soon."
