Very few hosts speak to 3.7 billion peers at the same time. Those
who do probably have dual stack. In most cases, the working set is
much smaller. After all, the existing Nat44 keep state, and they do
not explode.
Yes, but a NAT44 doesn't have to sync translation mappings with a NAT44.
I don't think IETF standardization for something like this is useful,
certainly not at this time.
