"According to an unnamed source, we have received word that Sony has developed a Peer to Peer (P2P) file sharing network that will allow users to seamlessly watch and share movies. There won’t be any hassles to deal with involving the use of the network. The system works on the premise that one simply downloads the specific file and the movie will automatically begin playing. To expand on this network, we’ve heard that they’re planning to integrate the service into “Home”, Sony’s new online avatar-driven platform. Creating this service and offering it within "Home" would only further Sony's attempts at offering the ultimate multi-media experience. As of now, this is only a rumor, we'll have to wait till Sony openly confirms this.
EDIT: I'd like to state that I listed this as a rumor because i'm still waiting to see what Sony/Grouper has to say. Our source says that this is VERY real though and that it's based off Groupers P2P technology, who as you all know was bought by Sony."
This would be pretty cool if sony can pull this off.
