I am about to write a femon patch for vdr-to-vdr streaming clients. I want to
make it possible for the client to see the signal information from the server.
Prototype which always shows the output of the primary device is already
working. Now I need to get the information which server dvbcard is currently
tuned to the clients channel. Still need to investigate the best way to do
this (cDevice::IsTunedToTransponder? Watching cStatus::ChannelSwitch? Check
the output of the femon INFO command once it is included? Anyone a better
idea?). With the correct card index I could then get the frontend information
if the femon SVDRP commands would accept the card index as parameter.

Will post the patch when I'm done, however it will still take a few weeks as I
have little time to work on it.

In my case the streaming client can do the stream analysis, so I won't need
the bitrates per device. Making this information available would have quite an
impact on the femon code anyway. However for the frontend commands it is
fairly easy.
