Hi,
I am not sure but are you suggesting that the IETF will define the
requirements, metric and quality assessment requirements and all proposed
codecs should provide the results and then the WG will choose the best codec
bases without discussing the codec itself. This is what I would call a
selection process (at least in ITU terms).
The problem is that the IETF process allows anyone to contribute to existing
work hopefully leading to a better the end result. 
What about the change control, does it stay with the original contributor or
can the IETF modify the codec based on input from other parties, which means
that the codec may change by the IETF anyhow. 
Thanks
Roni Even
