Start-ups blur lines between radio, music swapping

A new generation of start-ups is taking a page from Apple Computer's iTunes playbook, allowing Net radio listeners to draw their programming at will from one another's hard drives.

At the head of a movement that could transform online radio, Live365 and start-up Grouper are the latest to blur these lines between Internet radio and online song-swapping, with an alliance aimed at turning the older companies' stable of amateur broadcasters into the hubs of peer-to-peer communities.

The model looks to Apple's iTunes software, which lets people on the same network, such as in a dorm or office building, listen to songs from one another's music collections. Grouper's peer-to-peer service lets people stream songs at will to one another over the open Internet.

The company's alliance with Live365 is helping extend an advanced vision of Net radio already being pioneered by Mercora, another peer-to-peer radio service. By letting groups of listeners tap into one another's music collections, the companies hope to come close to providing on-demand radio services, while abiding by the strict legal rules governing online broadcasting.
