Dual stack works with "everything". IPv6 only access does not (with 
464XLAT it might). However, people are complaining that operators are 
focusing more on CGN and NAT44(4) than they are on IPv6. Which I can 
understand, but I believe we're getting closer to getting out of the dead 
lock. My hope is that 2013 is going to be the year we're going to see 
widespread IPv6 (dual stack) adoption on mobile devices outside of the US. 
It's looking good so far.

People are advocating dual stack now (at least that's what I do), for a 
future goal of IPv6 only.

The main problem with IPv6 only is that most app developers (most 
programmers totally) do not really have access to this, so no testing is 
being done.

IPv6 only is easy to setup if you already have dual stack.

On my Mac it is "System Preferences", "Network Preferences",
"Advanced", "TCP/IP", "IPv4 -> Off" then reboot to clear any lingering
IPv4 references.

It's about as easy on a Linux and a *BSD box.
