and in as much as we think
site-locals are bad we must provide a better alternative.
this kind of thinking is a dead end. we must not accept all of the
proposed uses of site-locals without question, because some of those
uses are the very source of the problem.
We need a way for sites to be internally stable even when their
relationship to the world around them changes for whatever reason.
see draft-moore-ipv6-prefix-substitution-aa-00.txt for one attempt to solve
this particular problem within a site. though I don't think it's sufficient
to solve it only "within" a site.
