No, I think it's neat.  I did something similar.  I have a pretty beefy 
backend that does all the flagging
and transcoding and went light on frontends.  My backend also does 
server duty for file storage,
asterisk, zoneminder, ftp/http, etc.  So far it's worked pretty well, 
other than my hdpvr crash that happened
recently.   I ran out of pci slots on my motherboard, so I went with a 
pci-expansion chassis formerly used in
a music studio.  The tuners don't seem to care.  I wish someone would 
release a card adapter for Dish network
so I could use DVB-S cards legally.  It would be a lot easier than HDPVR 
nonsense.
