it's easier still to run dual-stack hosts.  and there's a closure:
whenever it becomes reasonable for other reasons to run ipv6-only,
we won't need the 6to4 tunnels.  either way, in the short term the
thing most folks will actually do is either dual-stack or nat, since
either one of them is easier than 6to4 (with or without tunnels and
tunnel filters.)
