To flush out all the faulty implementations that could have been updated
already in the last three years.

IRC users don't care about this. All the IRCd's of at least the bigger
networks have already been upgraded at least 2 years ago. FYI
irc.song.fi only uses ip6.arpa while several others first try ip6.arpa
and then fallback to ip6.int. The reason they had to have a fallback
mechanism is because of the ip6.int still being used by 6bone and there
was, for those users, no alternative, there is now thus let's get rid of
it.

Some, but then again not every train supports IPv6 that well either ;)
Apparently it is very hard to do s/ip6.int/ip6.arpa/g for even a company
like Cisco...

Then again, how hard does your 'production router' depend on the
existence of ip6.int. It is no server and your logs will now show the
IPv6 addresses. Is this a problem? IMHO absolutely not.
Complain to your vendor that they are late.

See http://www.sixxs.net/forum/?msg=general-83948 these 'real customers'
like the idea very well, they might not be paying for the service but
they do like that it works and believe me they do complain when it does
not even though they get it for free. Fortunately the problems are
minimal and don't happen that much and we already announced to pull the
plug on ip6.int some time ago when this event (e.f.f.3.arpa going live)
would occur. Also there is something called 'maintenance' that goes very
well when upgrading machines, of course after you tested them in your
non-production testbed.

That is what Microsoft demands from them, read their EULA's.
XP's IIS for instance is capped at 10 concurrent threads etc.
There is a reason why they call it 'home' and 'server', just like you
have MAC OS X Server and Redhat Enterprise. You get what you pay for.

All the production 'stuff' is running in RIR space and RIR space has had
ip6.arpa since the beginning of ip6.arpa. Thus that is a non issue.
