This looks like a reasonable start.  I'm not sure why there are so
many other sections in the document.  It was pretty clear to me that
consensus was reached around the use of Binding requests.  I'd suggest
that you trim the document down to just this section if you intend for
it to be adopted.

There needs to be more detail about the nature of the consent/liveness
test with respect to the observed round trip time and packet loss.
Based on the discussions at the interim, it was clear that the
complete 60+ second check time was unnecessary for consent/liveness
refresh.

I can see how you might reach the conclusion that consent is not
needed for RTCP flows, but I don't see the benefit of creating a
special case for it.
