And clearly that situation can be kept that way for a long time by simply not serving them anything over IPv6.

But is that wat we want?

Currently IPv4 is pretty good but that's not going to last once 1.5 NATs on average between any two points grows to 3.8 of them, with 1.7 starved for address/port combinations*. At that point you can technically still be 100% connected using just IPv4, but it won't be much fun anymore.

* numbers pulled out of the air by yours truly, but based on two consumers with home NAT today and with additional carrier NAT in the future.

I've been on IPv6 for a long time. When I started with IPv6, the only applications (to use the term loosely) that understood v6 were ping6 and traceroute6. These days, I think the only thing I wouldn't be able to do over IPv6 is print. It used to be that IPv6 pingtimes were 2 - 3 times worse than IPv4 pingtimes. They're pretty much the same 80% of the time now. I used to have 8 IPv4 addresses, enough for most of my computers. I have one now, with mandatory NAT. When I move later this year I may very well only have a partial IPv4 address.

The times are a-changing.
