Silent Broadcast Party

Imagine a large gathering of people dancing the night away to a variety of simultaneous DJs- without disturbing the surrounding neighborhood. Various DJs (using iPods or otherwise) broadcast programming over multiple FM channels to FM headset wearing participants. You could be dancing to Old School Funk right next to your Electronica neighbor. You'd also have the option of taking your headset off and having a voice level conversation. Especially in conjunction with a flashmob event- where the noise of speakers would bring the law instantaneously- this silent FM broadcast method would no doubt buy the party a lot of time and might well remove the policeable aspect of such an event. Plus it would be a lot of fun to look at!
