The thing I worry about with cloud based DVR's is speed. I've used the DirecTV multi-room DVR's before and they were always very slow in response.
Speed would be my main concern too. Even just using the multi-room DVR functionality - accessing the DVR from other boxes usually has a delayed response when using FFW, REW, Pause, etc. I would expect it to be much worse with a cloud-based DVR.
