Here comes P2P Radio

A few weeks ago, I got a chance to chat with Srivats Sampat, the former chief executive of McAfee.com. These days he is running Mercora, which is an interesting twist on P2P music revolution. One of Mercora's co-founders is Michael Stokes, who developed the Gnutella 2 platform. Mercora is a small little application, which you download and install on your computer. It scans your hard drive, looks for all sorts of music files - Mp3, Ogg Vorbis, WMA - and builds a tiny database. Then you send invites to your pals, inviting them to join your buddy list. Once they join your buddy list, they can listen and control a special playlist that you create for them. Think of it as a nano-radio station that webcasts music to anyone musically using a peer to peer technology.

The Mac ITunes users, thanks to the Rendezvous technology, can share music on their local networks but not over the Internet. Mercora, has taken that concept and globalized by connecting it over the Internet. I-Mesh and ShoutCast are doing similar stuff, but their architecture is client-to-client P2P. The architecture of Mercora network mimics Napster's server centric architecture. The music streams through a Mercora proxy which maintains the bit rate, and the sound quality is surprisingly clear. Mercora application is as easy to use and intuitive as Napster, minus the downloading, and it can webcast music at 48 kilobits per second. "It is an optimal quality and bandwidth trade off. We use direct X codec for transmission and playback of music. On a typical DSL connection you can do this quite well," says Sampat. "We use the DirectX to compress the bits and send it out as WMA."
