> front-of-house mixing console and the other the combined signal from
> two room mics) so I would like to have two separate mono RTP streams.

> module-rtp send, so a mono rtp stream can come from any channel of the
> source, instead of only the mono channel.
> Which approach would be preferable? I could see the value in
> implementing both (eventually). A new module-remap-source would fix an
> obvious gap in the symmetry between sinks and sources, and could
> potentionally be useful in other scenario's too. I think I saw a bug
> report about the lack of a channel_map parameter for module-rtp-sink,
> so adding that to both rtp modules would be good too.
> Any thoughts on which steps to take?
