why IPv6 isn't ready for prime time, SMTP edition

Maybe you should focus on delivering email instead of refusing it.  Or just keep refusing it and trying to bill people for it, until you make yourself irrelevant.  The ISP based email made more sense when most end users - the people that we serve - didn't have persistent internet connections.  Today, most users are always connected, and can receive email directly to our own computers, without a middle man.  With IPv6 it's totally feasible since unique addressing is no longer a problem - there's no reason why every user can't have their own MTA.  The problem is that there are many people who are making money off of email - whether it's the sending of mail or the blocking of it - and so they're very interested in breaking direct email to get 'the users' to rely on them.  It should be entirely possible to build 'webmail' into home user CPEs or dedicated mailbox appliances, and let everyone deal with their own email delivery.  The idea of having to pay other people to host email for you is as obsolete as NAT-for-security, and this IPv6 SMTP thread is basically covering the same ground.  It boils down to: we have an old crappy system that works, and we don't want to change, because we've come to rely on the flaws of it and don't want them fixed.  In the email case, people have figured out how to make money doing it, so they certainly want to keep their control over it.

If an enduser gets a bill for sending several thousand e-mails because they got owned by a botnet they're going to do something about it; get enough endusers with this problem and you'll get a class-action suit against OS vendors that allow the problem to remain a problem; you can get rid of the bots.  This will trim out a large part of spam, and those hosts that insist on sending unsolicited bulk e-mail will get billed for it.  That would also eliminate a lot of traffic on e-mail lists, too, if the subscribers had to pay the costs for each message sent to a list; I wonder what the cost would be for each post to a list the size of this one.  If spam ceases to be profitable, it will stop.
