An actor can be in one of several states:
You rigged the list of states. There is more than one possible state
that include IPv6 connected as the baseline. For instance, IPv6
connected with access to 6/4 web proxy and 6/4 smtp forwarder. There are
other possibilities. Consider a large community of users (community
meaning they communicate a lot with each other) who have such an IPv6
service. They can freely use IPv6 supporting applications with no NAT
worries. Access to the v4 Internet is restricted but no more so than in
the average v4 corporate network. Now what if that large community of
users is a country where people do not speak one of the world's top ten
languages.
The game is too complex for game theory to analyze since it is too hard
to get the right list of states.
Rather than fight the dynamics of a market with a billion
participants I believe that we should embrace them and
remember that taking IPv4 to end of life is not exactly an
unacceptable outcome. The key is to channel people into
IPv4-NAT/IPv6 rather than IPv4-NAT.
I would be slightly less specific and say that we should channel people
into IPv6-gateway-IPv4, meaning that they get IPv6 connectivity but some
sort of gateway support services to access IPv4 hosts. Those gateway
support services will probably be a whole smorgasbord of things
including Teredo and simple dual-stack proxy servers. Perhaps the
pioneers will be those ISPs who currently offer some sort of
managed/restricted service such as Family Safe Internet or Christian
Net. It doesn't matter who takes the first steps. Once the technical
principle is shown to be workable and profitable, others will adopt it.
The way that I would go about this is to introduce a gold
standard for next generation gateways that provide other
features that the consumer is likely to consider desirable.
Like being maintenance free, working without the complaints
and setup time that current devices require.
I agree that those are desirable goals for the gateway standard.
