For those of you wondering what the hell I'm talking about, OnLive is a service that allows you to stream games directly onto your computer or TV without a console or purchasing hard copies of the game. For more information on the details of the service itself check here.
The service is priced at $14.95 a month with unspecified price breaks for multi-month purchases.

"Instant-play free game demos; multiplayer across PC, Mac and TV platforms; massive spectating; viewing of Brag Clips™ video capture and posting; and cloud-saving of games you’ve purchased—pause, and instantly resume from anywhere, even on a different platform.Check out the full official article and pre-register for a chance to win three months of service free.
Also included in the monthly service fee are features you’d expect from standard online games services such as gamer tags, user profiles, friends, chat, but with a twist: everything is live video. You’ll be friending through multiplay, Spectating, Brag Clips, or by flipping through video profiles of friends of friends of friends. OnLive is delivering the first instant video-based social network. It’s really cool."
