=> *personally* I don't like 6to4 because this is far too close to
automatic tunnel / compatible address stuff which was proved to
be a bad idea.

   Not to disagree, but just to observe that there are many Internet
   subscribers who do not have even one globally-unique IPv4 address --
   they only get temporary use of one from a shared pool when they
   "login to the Internet".
   
=> you can easily change the shared-temporary IPv4 address for
a globally-unique IPv6 one (draft-ietf-ngtrans-hometun-00.txt).
IPv6 is for users at home too, even if they don't know it today...

PS: perhaps I should present my draft at a ngtrans session and
implement it (:-)...
