Ok.

But the questions (that haven't been answered properly, or asked for that
matter) are, "does this have to be done now?" and "do we know _yet_ that
this approach is the best one in the long run?").

Again, I'd say "no".  For the next very many years (unless something
unexpected happends) we'd be able to manage just fine with dual-stack.

Some additional methods will probably be necessary when the IPv6 usage
nears the majority of the Internet use (and consequently IPv4 sites are
clouds in the Ipv6 Internet), but until then I'm not sure if it is worth
designing complex systems to handle certain issues when they could be
worked around by good design.  Just as ngtrans isn't worrying about "4to6"
or similar scenarios (at least yet) either.
