Ted, Thanks for the comments and reply.
Again, the draft is not about building one large Layer 2. The proposed proxy gateway is to enable subnets not to be restricted physically together, i.e. allowing the gateway nodes in one access domain to be the "proxy gateway" for all the hosts attached regardless those hosts' subnets. The draft is allow all the hosts attached to one "gateway" to be represented by this gateway, very much like today's router represent all the hosts attached. As for L2 NAT mentioned in the draft, there are issues and the benefits. The benefits have been documented in the draft and many of our emails. The issues need to be addressed. That is why we would like the WG to contribute. There are a lot of issues with L3 NAT too, but L3 NAT is one of the key components that make today's internet scale.
