I don't think that the ability to have multiple servers on the same port is significant enough to trigger a migration; there would need to be a more significant change. Bottom line is that on my single IP at home, I host all the services I want, use H.323, peer-to-peer apps, and whatever else I please and yes it does work. The annoyance at this point in time is manual configuration to make it work, but with things such as UPNP and STUN it gets easier and easier. If we were in a world where we did not need stateful firewalls, NAT would be a lot more of a hassle than it is today; unfortunately dealing with a stateful firewall with or without NAT is about the same amount of work, so NAT is here to stay. I have to say that given the recent trends and developments, I am now on the fence WRT joining the camp that says that NAT is unavoidable for v6 so we might as well make it work. I have not made my mind yet but if things continue the way they are now you will likely find me developing a NATv6 box this time next year.
