Is there *one* tunnel management protocol that they all support or
does a cpe vendor have to implement multiple ones to reach them
all?  I'm pretty sure I know the answer to this question but I'd
love to be proved wrong.

One of the advantages of 6to4 anycast is that it is just needs a
check box to turn on and off.  Everybody speaks the same thing.

Another advantage of 6to4 is it doesn't require manual intervention
on renumber events.  Manual tunnel don't pass muster.

Another advantage of 6to4 is you don't have to register.  For most of
the tunnel brokers you have to register.
