iCast - mp3 radiostation player

Problem context :

This is a very simple idea :)

Imagine your iPod or any other mp3 player, and it's empty. You haven't bought or copied any music yet. But now, you want to listen a music. Than you go in the bus, subway, university or work, and press the bluetooth-receive button. You immediately scan the area for any other mp3 player able to broadcast their music - you hook up on it, and now, you can listen to music in their collection. Sure, you can't download their music - it would be against the law.

In few words, if can broadcast your music over the bluetooth to other "iCasts" owners, and you can listen to somebody else music.

I am an informatics student, and based on things i know about the bluetooth I think the technology behind this is not so complicated. The following quotes are from wiki about Bluetooth.

 "The [Bluetooth] devices use a radio communications system, so they do not have to be in line of sight of each other, and can even be in other rooms, as long as the received transmission is powerful enough."

Now the maximum of devices paired to yours are:
"These days, a piconet is an ad-hoc computer network of devices using Bluetooth technology protocols to allow one master device to interconnect with up to seven active slave devices (because a three-bit MAC address is used). Up to 255 further slave devices can be inactive, or parked, which the master device can bring into active status at any time."

I hope you all have understood what I was trying to say :)
