I have to be honest. I didn’t think much of the TV Everywhere plans laid out by Comcast and Time Warner last month, but the service sure has my attention now. Soon – like in a few weeks – 5,000 beta testers will be able to watch TBS, TNT, Stars, HBO, and Cinemax content on Fancast.com or Comcast.net along with the content already available from ABC, NBC, FX, and more. Eventually, the plan is to open the service up to all subscribers of Comcast and Time Warner for “no additional cost.”

We still have questions about the authentication system and if the service will have an open API that will allow developers to build it into streaming software PlayOn or Boxee. Those details will probably drop later, but if Comcast can continue to add premium content online from the big names, they might be onto something. Now, how about Showtime for some Californication and Weeds action.
