Sure thing, I've already done some of those, but it won't really change
much.  There's no real reason for a end-user to contact my SMTP or DNS
servers directly, as he will normally relay e-mail/DNS queries via his
own ISPs servers anyway.  And the fact that all the workstations at my
office have native IPv6 connectivity doesn't have any effect on all the
broken end users in other networks.

The problematic service is without question the web sites.

Absolutely.  I'm sure that at some point in the future there'll be more
end users able to connect to a dualstacked web site than there is end
users able to connect to a IPv4-only site.  At that point you'll see
lots of IPv6 content showing up.  No problem.

However, when will that point in time be?  The way it's going right now
it seems to me that it will be well after IPv4 pool is exhausted, when
the IPv4 internet is starting really to crumble under CGNs and other
life-extending band-aids.  I'm more impatient than that though, and
don't want to just sit around and wait until then.  It appears other
content providers like Yahoo and Google don't either.  But short of
resorting to DNS tricks, or attempting to persuade all the end users'
ISPs and/or software vendors to fix their problems, I really don't see
what else can be done.

By the way I actively pursue the option of asking problematic networks
and software vendors to fix their problems.  It's a very slow process,
though.  Even when software patches are released, it takes lots of time
before a sufficient amount of end-users have applied them.

Best regards,
