Students concoct music industry's nightmare

A group of students at the Viktoria Institute in Gothenburg, Sweden, has worked out a system of P2P music listening and sharing that will make the head of the RIAA wake up in the night in a cold sweat.

The students have developed something they call Push!Music. This is a mobile, peer-to-peer music listening and sharing application.

It runs on WiFi-enabled PDAs and allows users to actively recommend songs by pushing music to other users in the proximity.

You might be walking down the street and a complete stranger, who happens to have the same music taste as you stored on his PDA, might send you some tracks that his machine knows you are missing.

Meanwhile you would be opening your entire music collection to everyone within wi-fi range to borrow.
