IPv6 is just fine. The problem is not the technology we would transition to, it is the lack of transition strategy and refusal to think about deployment strategy in some quarters. While they were building the big dig in Boston they actually built an entire interchange from scratch and then demolished it. The temporary interchange was necessary because you can't stop traffic in Boston for ten years while you build the permanent one. We need the same for IPv6. The problem with IPv4 address space exhaustion is that it is much less of a problem for end users than some imagine. If you have an IPV4 address and someone else does not, that is their problem, not something you want to spend money for.
