(Careful, there is a wrong reference to RFC 4860 in the Register article - where they probably mean 4862)
What’s more interesting though are the 50+ comments, of which a big chunk revolves around the NAT subject and IPv6 design (failures).
The irony is true however, that "one of the reasons it took such a long time to nail down IPv6 was the amount of effort that went in to the mobility problem - making sure your address (and the traffic routed to it) followed you round as you moved."
