(My use is a bit linux influenced)

I would like to encode multiple channels of audio, the input being for 
instance
- a multichannel (wav) file
- n jack sources

And in the end stream low latency over RTP (for instance in a Gstreamer 
pipeline); currently I use vorbis, and although it is very convenient 
channelwise, the added latency is too high to be of use and I need 
compression to keep the bandwith reasonable.

As I understand it now I will have to write both the interleaving bit 
and the celt n channel rtp payloader.

Best, Dirk
