I guess that should work on a headless streaming server like mine when I add
the dummydevice plugin and set the primary device to it, right? Without dummy
device it won't tune to a different channel if the primary device is
recording. Might work for me, so I will give it a try.

But in case more people are interested in it: what would happen on a server
with someone watching live TV on the FF card and the client streaming from the
budget card? Can't test it as I have no FF card, but I guess the SVDRP CHAN
command would change the channel visible on the server. Could be annoying if
the guy behind the client loves femon statistics...

I have it running that way at home. Getting the card index was easy that way
as of course streamdev-server knows it. But I also had to extend the femon
service interface to get the information by card index. I don't like this
solution as it requires patching streamdev-server, streamdev-client and femon.
 That's why I decided to rewrite the whole thing based on SVDRP and trying to
patch femon only.
