There are others (e.g. three I know of in the UK).  How public they are
is another issue.

Just to put 6to4 in perspective for its current deployment, I am not aware
of any European NRENs that are using 6to4 to connect sites to their national
IPv6 deployments.  Everything is done by manually configured tunnels.

That's not to say 6to4 doesn't have a place (our students use it for access
from their home networks, and it will work behind a NAT with tunnel forwarding)
but it is perhaps more likely to be in large customer networks?

To play devil's advocate, who is using 6to4 in a notable deployment?
