You don't have to like it, but IPv6 NAT is already happening. Wishing
it would go away won't make it happen...

We're using ULA for our lab here, with the very explicit goal that the
boxes in question should *not* connect to the Internet. We're not using
IPv6 NAT, but I can certainly see the point of what Saku Ytti suggested.
