Tunnels are just one of the _transitions methods_ for the endusers,
that they where also used to bind together the 6bone is something else.
The bigger and IPv6 aware ISP's are quickly moving out of that, read:

I also am wondering how people define "multihoming".
Do they define it as:
 - Multiple prefixes over multiple cables from multiple upstreams.
 - One prefix over multiple cables from multiple upstreams.
 - One prefix over one cable from multiple upstreams.

If you are talking about the last case, where one only has one
physical upstream... one shouldn't call that multihoming.
I guess the second one is where people are talking about.
And the first one is what I would call real multihoming,
though one needs SCTP to make that work.
