An entire-home DVR will not be an island unto itself; it leverages the RVU protocol to extend its service into the other rooms of your house.

While RVU is now part of DLNA, there isn't a lot compatible hardware in the marketplace. DirecTV included a number of Genie Mini Clients (C31) for us to evaluation, however as talked about earlier, there are also a number of compatible Samsung TVs (2011's D6000 and most 2012 models).
