> The big "win" here is that existing IPv4 routers in the Internet's core infrastructure do not need to be upgraded all at once.
As I understand it, that is not the limiting factor in IPv6. Actually, I believe it was the second piece of the Internet's infrastructure to support IPv6 (the first part being OS networking support). Instead, the limiting factor is network management and middleware, in other words the edges and not the core of the Internet, that are holding back IPv6 adoption.
