Thanks for the answers, everyone, very interesting.

They'll give out /20s (to ISPs) and perhaps smaller to end users, if you
can justify it. I heard a talk where a university needed to block
traffic to one IP. But they couldn't do it with BGP (which would have
blocked the traffic at the source) because of routing table sizes.

Well, $2500/yr isn't the end of the world. Interesting that in IPv6 you
can get a /32 for $2500/yr. But not if you're an end user and you have
to dole out 200 /48s in the first 2 years. And your $2500/yr is a
"license fee" so your addresses may be changed (or revoked) at someone's
whim (ARIN's? I'm not sure). Certainly not a big deal practically, but
something to note for super-paranoid libertarian types.
So if a /32 costs $2500/yr then a /48 should cost 3.8 cents/yr (plus
administrative overhead so something like the same as you pay for your
domain name). Or perhaps so much less than your bandwidth costs that
every Internet connection comes with at least a /48 (that's globally
routable addresses). Be interesting to see if the providers see it that
way.

Yeah, I have little hope of having an IPv6 capable ISP before 80% of the
world does. Be fun to play with though, even if tunneled.
DoD is pushing IPv6 for 2008 so that might get things moving. My office
is planning to convert from global IPv4 addresses to private addresses
soon. This is perceived to make it easier to set up an enterprise wide
WAN (for security and Active Directory purposes). I suggested that we
just go with IPv6 (rather than doing the enterprise wide readdressing
again in 5 or so years). But beyond "we'll all be retired in 5 years so
it'll be your problem then" I don't get much discussion on the subject.
Thanks for listening.
