According to Apple Insider, iTunes 8 may include a streaming service, reportedly named iTunes Replay, that will allow users to access their purchases anywhere they are logged in, possibly including (crossed fingers) the iPhone, iPod, and Apple TV. Such a service, which would only require wireless access, would solve the  limitations of iPhone and iPod in holding video files and streamline the process of transferring files to the TV unit. The only question remains whether Apple will provide this service to its users for free, or charge for it via a subscription fee. Really, though, is any price too great for the assurance that, wherever there is wireless, all your episodes of Battlestar Galactica are at your fingertips? I think not. [ARS Technica]
