The problem is that turning on v6, while requiring
that v4 continue to work means accepting the
limitations and security risks of both protocols.
This is not a "transition" - this is another level of
indirection (c.f. RFC 1925). A "transition" has an
end-state which is clearly defined, and we are only
just starting to ferret out the end-state with regard
to v6.

That's what you mean by "IPv6-only"? When I talk
about IPv6-only, what I mean is "no other layer-3
protocols running: no IPv4, no Appletalk, no IPX,
etc."
I get that there is rough consensus. I'm waiting for
the running code.
