For me, IPv6 has always been about "IPv4 does not have enough addresses,
and as a consequence of that, pain and avoidable cost ensues".
Thus, I'm not sure we do ourselves a favour by making IPv4-cludges so good
that the pain is hidden well enough - the fact that Kabel Deutschland is
breaking SIP is causing quite a bit of pain at one of the bigger german
SIP providers, who are rumoured to look into IPv6 deployment now...

I can see that, and of course I have that for IPv4 already :-) - but
I claim that this is actually not something most (for wild handwaving
values of "most") users want, given that normal end users just don't
run services at home, might not even have always-on components at all
(readers of this list are not "normal end users", your parents might be).
One of the major benefits of IPv6 I see for SOHO users is the homenet
architecture with multihoming, SADR and service/ISP selection *by the
application* ("use cable ISP for bittorrent, use DSL for web browsing").
We're not there yet, though...
have you enabled IPv6 on something today...?
