given the relative ease of acquiring v6 address space and the
relative ease of deploying v4+v6 end hosts and either v4+v6 campuses
or v6 tunnels in v4 campuses, there is no incentive to do nat/v4 any
more, and precious little incentive to do nonat/v4.
*I* can get v6 connectivity easily (heck, I just boot my laptop and ...
Now, having done that, I can either jump through lots of hassles
configuring a 6to4 proxy, or I can just type www.cnn.com in the
browser window.
It isn't just whether *I* can/have done it, it's *also* about whether
the resource I'm trying to contact sees ipv6 as something that needs
doing.
unless you're aware of different natural laws than i am, somebody will
have to go first. i realize that there's more motivation in going
second, but still, somebody will have to go first, or by definition
nobody will be able to go second.
being first gets a whole lot easier as more dual-stack hosts come online,
thus requiring less motivation from those who could possibly be first.
(certainly less motivation than being first if it means runningv6-only
and finding a 6to4 proxy.)
so the "relative ease" of getting v6 address space and of running dual
stack really is directly relevant to whether v6 will ever reach "the
tipping point."
