Not an ostrich here, http://groups.google.com/group/tmoipv6beta.
IPv6-only + NAT64 is alive.

I don't believe this is a true statement.  Simply having the ability
to configure an IPv4 address on your system does not mean that you
have an IPv4 address to use.  The point of IPv6-only is that IPv4 is
exhausted.  Given that dual-stack has not seamlessly transitioned us
to IPv6 as it was envisioned 10 years ago, demand for IPv4 will soon
exceed supply. Hence, IPv6-only solutions.

My customers, cell phone consumers, are generally not interested in
IPv4 or IPv6 or Dual-stack.   They just want it to work.  If I do not
have the IPv4 addresses (public, private, bogon), the service will not
work.

I believe there are 2 separate problems one is in the access network
and one is in the content network.

If the access network is growing (anything mobile, devices in the home
like DVR ...), they need to move to IPv6 as soon as possible since
IPv4 is not growing.  It is a simple business continuity story.  If
the access network is not growing, the business case is less urgent,
but a good idea.

For content providers, they NEED to be dual stack to reach all their
possible eyeballs.  Once again, it is a simple business continuity
story.  Without dual-stack (from a service perspective), you will not
have the best method of reaching all your customers.
