I find it unlikely in the extreme that a bunch of engineers will sit
around in an ietf meeting and dream up a new audio codec. instead
inviduals will bring existing work into a working group, where it will
be accepted or not based on the charter, interest in the work etc.

To pick out speex for example audio codec geeks know the history of
celp, they also know the history of the development of speex by
Jean-Marc Valin. that's fairly congruent with my expectations as to how
this process would work on the front-end.

Show up with draft text and running code is vastly prefered to starting
with nothing.
