Stared at the IETF drafts section. Gah. How the hell do you find
anything in there?
Quote from RFC 1883 (or 2460, for that matter):
And a new type
of address called an "anycast address" is defined, used to send
a packet to any one of a group of nodes.

But a lot of the work has been done.
Linux supports it. Apache has patches which do, but that currently conflict
with virtual hosting. Squid does. SSH does. Perl doesn't yet.
There are mailservers, FTP software, and all sorts of other things
which have IPV6 built in.
It'll probably be a lot more deployed once Apache supports it
It might take till M$ does - but OTOH, maybe we tech-types could
all slip over to the IPV6 network and leave the commercial crud
on the 'old' internet....
