Imagine if there was some kind of central digital rights management system, that simply kept track of which shows and movies a consumer had purchased/leased the right to see, and then they got to legally see it from wherever they pleased, including bittorrent. Forcibly (by regulation I imagine) separating the "negotiating licensing deals with rights-holders" businesses from the "delivering video to the consumers" businesses. You could stick to whatever delivery platform you preferred, maybe get a marketplace to see the cheapest options to get to view the video you wanted if it wasn't already included in any of your current subscriptions.
