There are more fundamental changes required to spark wide-spread
deployment of IPv6. 

* a v6-only "killer application"

* or a real shortage of v4 addresses

* or some other real advantage of v6 over v4, financial and/or technical

However, most important is that those involved with v6 need to
understand that it's impossible to foresee and solve all future
problems. Till then IPv6 isn't mature enough to go anywhere. Any
successor to IPv4 has to provide similar ability to evolve over time,
and operational policies have to evolve with it. 

IPv6 as it stand has a lot of room for improvement but that doesn't make
it useless. An important aspect of engineering is to take what you've
got and make the most of it. Where would we be today if early IPv4
implementations had been halted because there was no DNS, no IGP and no
EGP? There was even an internet before we got CIDR ;-)
