Hi Tommy,

Thanks for the response.  I'll comment below.

That may not be the intent of the IAB.  However, that is what will 
happen as you (used in general terms) get in working group details.

If you ask about that during a review (unrelated to the proposed 
program) you'll most likely get the "it's the consensus" or some 
other answer which does not explain the how.

The implementers, with some exceptions, do not have much of a say in

Who are the people responsible for evolving the Internet?
