Innovative peer-to-peer-based internet television service, Joost, has opened up for business following an extended beta-testing period.

Joost is an internet TV service for Macs and PCs which has reached deals to distribute programmes from various small to medium television channels.

The software - which uses a peer-to-peer network to distribute shows - has been made available as a free download.

The new version offers automatic notifications when new content is added to the service, the ability to link directly to video and a built in software update mechanism to keep the Mac client up-to-date.
