[vdr] Centralized VDR solution?

Hi,

I've been thinking of a PVR solution where all DVB cards are installed on a server and several clients connect to it. Each client must behave like they are in control (normal menu operations even though most likely a bit slower due network delays). Of course the number of DVB cards define the limit how many different muxes are available or how many crypted channels can be viewed at a time but those are understandable limits.

There would be at least 2 clients but most likely later on 4+ clients. Clients would be without HD most likely (network or USB stick boot).

Is there a solution (reliable) for this kind of system available?

Br, Pasi
