Hey Owen,

Its  encouraging that progress and momentum continues, but there is no 
way to be 100% confident that IPv6 has unlimited time to obtain dominance.

There were still plenty of opportunities to save the day that IPv6 
global deployment missed.

There were more mile markers than NAT on the address shortage problem 
route and IPv6 failed most of those as well. Some of those happened 
early, some not so much and there are probably more to come.

While shortage might have been the main driver of development of NAT, 
provider independence and abstraction was the clear motivation for end 
users to adopt it.

20 years ago it was not considered optimistic to expect that there would 
no longer be threads of this nature, it was essentially treated as 
heretical to imagine there might be. And there were concrete 
consequences to that mode of group think.

Even a naysayer as myself, back in 2004 really only expected another 
decade or so of transition to clear dominance.

I will note that a decade to make 240/4 usable was cited as a major 
opposition reason to it. And other ideas.
