I concur with the others as this is a problem space that needs to be
addressed. Personally, I would be interested in feedback related to the
management protocols (SNMP, netconf) in this regard.

I think it is important to discuss this problem space, as there are a
number of completely different approaches already being developed,
including STUN/ICE/whatever and IPsec with NAT-T.  Whether the proposed
approach is a good addition to the set is something that could clearly
be discussed in a BOF.
