Don't ge me wrong, NAT does not work very well. We still need v6.
Bridging IPv4 and IPv6 is a temporary/transition solution.
So the idea is:
- use v6, you'll have end to end connectivity between v6 nodes.
- but you still want to maintain some level of interoperability
  with v4, but don't expect miracles there.
  NAT is not a very good answer, but it is the best we have so far.
