First of all: there are MANY problematic patents (as in illegal) that
would make about everything bind to them. So even if you see certain
claims be sure that you will find somebody that holds a patent about the
procedure you are using (eg, Vorbis vs Thompson)

You mean snow, nobody is sure about wavelet patents around.

maybe sonic? (Keep in mind that is just an experimental codec that isn't
working so bad as an experiment)

Nut is a container, yes =)

You should ask Alex since he was working on something about that. vorbis
 supports already multiple channels.

snow should handle that nicely IMHO.

I'm more or less working on the same topics for my master thesis, but
I'm focused on streaming and standards on streaming instead on hw
encoders. Probably we could do some work together.
