There's no technical reason an RVU client couldn't be built that recreated a PIP or Doubleplay scenario. As far as any server is concerned, a port or IP/port combination is a unique client. So, if DirecTV allowed it, a single client box could request 2 separate RVU streams. Bam... two TV streams and PIP we have. If DirecTV didn't allow it, all the client would have to do is generate a second MAC address and request a second IP address (either physical or virtual) and DirecTV would have no idea it was for a single client. Then the client would render and be responsible for creating the PIP - but the source would all be a single HR34. So... lots of ways to do it.
