Well, quite big changes would have to made.

A network interface should be added between backend/frontend, so that a 
VDR client could connect into a VDR server, and use its data directly 
(caching implemented where desired), i.e. for EPG, recordings, timers, 
etc. Quite a bit of work would be needed for that separation.

This is further complicated by the need of having to use DVB cards which 
are located in hosts running separate VDR instances, possibly requiring 
defining one VDR instance as a master backend server, which handles 
allocating the devices on different hosts, etc.
