One issue I could see with that.
How do you esnure that two clients don't try and schedule the same show to record.
Or you "recorded" a show on one client (say the living room) and now want to watch it in the bedroom.
Do you have a feature to see local and then all?
Concept from Verizon is that the VMS (Video Media Server) is a server to service everything.
That is why the concept of the clients was developed.
Put all the smarts in one central lcoation and have all of the remotes stream from it.
This allows you to start a program on one client and resume it on another for example.
