PodLink!

http://www.youtube.com/watch?v=b9E0jS-wI60PodLink enables you to wirelessly control the music playing on another iPhone, iPad, or iPod touch running PodLink. Plug in one device (in sharing mode) to a stereo or docking station, and control it remotely with multiple other devices using Wi-Fi or bluetooth as if you were holding the device in front of you. Special thanks to our professor, Elliot Solloway, and Alex Kuhn.
