CAM is not a user specific setting, but channel specific.
DiSEqC will soon be replaced by a "source" parameter (haven't decided on
the name yet), so it is also channel specific.

The problem is that you need a way of telling which user channel is which
channels.conf channel. In order to do so you'll probably need to repeat
many of the parameters stored in channels.conf. To safely identify a channel
I guess you'll need the "source" (sat position, cable, terrestrial), the transponder
frequency and the service id (assuming service ids are unique within one transponder).
And in order to store separate volume levels for each APID you'll even have to
repeat the APIDs in your user channel setup. I'm afraid this would in the end
make things unnecessarily complicated.

I've yet to see a good concept for a "user channel settings" list that doesn't
duplicate most of the information in channels.conf.
