Second I want to make perfect clear that I have no doubts about how serious IPv6 is, and how urgent we need to do it.

But Job you are perfectly right, this topic most of us has come over multiple times, and I am sorry to bring this up again.
No, do not feel sorry, IP economics change over time. Especially given that World IPv6 Laundry day is around the corner, it's worth discussing.
As I have been to Asian a lot, which is the first region out of IP spaces, but I find out most of my Chinese colleagues have never worried about IP issues. Even China telecom are charging over 10USD/month/IP, most ISP are just ok with it. because end of the day, 10USD/month isn't a lot for enterprise customer.
You are talking about _today_ I assume. I think at some point the cost of maintaining IPv4 space will be higher than just deploying IPv6 on the devices that talk to other continents.
NAT has limited functionality, yes, but for most cable network users, that functionality is enough for them.
Might be true, but I like a world where everybody can run any service on their IP addresses without jumping through NAT hoops. Kind regards, Job
