"If".  But this is not so, and therefore, 6to4 with anycast relay is
just not something that makes sense for global traffic.

Our (well-maintained!!) 6to4 relay works very well for traffic between
our users and our IPv6-enabled machines - but as soon as the users have 
native IPv6, no more need for the relay...
