Thanks for an impressive list of reference links!

So, this is all quite interesting. Sounds like there are commonalities
to our proposal.

I'm in favor of keeping the focus limited at any one time, but
rechartering is fine when some things get done. But what other QoS
enforcement mechanisms did you have in mind besides diffserv?

It would be nice if someone could attend. We don't have a very long time
slot, so perhaps we could find some time to get together in addition
to the BoF.
