A little while ago, Apple released the iPod Camera Connector which allows you to connect your camera directly to an iPod Photo and download it’s contents.
It would be cool if it worked in reverse with an iPod Shuffle, allowing you to dump a random assortment of songs from an iPod onto the Shuffle. Imagine running into a friend with an iPod, plugging your Shuffle directly into their iPod and walking away with a different music experience.
It would work well within the ‘random music’ framework that Apple is pimping for the shuffle. It also takes the idea of jacking into someone else iPod to the next level.
