  Do we really want customers of NAT devices to be happy?

I think we want to enable an Internet that works and serves the needs of its users. We are still going to be seeing IPv4 on the network for a while still, and I believe it is worth our time to make sure that new applications can more easily be built for that network.

During the BoF session, there were folks from many of the major vendors of such devices, and those folks said that they felt that the IETF recommendations on NAT behavior stood a good chance of being implemented.

  I don't think we need a working group to say this.
  I think that the IAB could write a document much easier that said

I think the work to be done is far more complicated than just saying "don't break teredo". There is a lot of variability in NAT treatment of fundamental IP protocols - UDP, TCP, etc. Nailing down these variabilities can make applications more robust, more secure, and easier to design and deploy - a goal I think we all share.
