View DVR recorded shows in other rooms

I thought I had seen something awhile ago saying that the day would come where you could record a show on your HD DVR and then be able to watch it on another DTV HD box in the house. I assume this is not yet possible. Has anyone heard if this is actually coming? I assume this would be another use of connecting your DTV boxes to your home network?

MRV (multi-room viewing) is rumored to be in the works. It would use the home network connections to allow sharing of recordings.
