I don't agree, if you are an accessproivder I think it would there is
one very important thing you can do or if you not yet able to do the
next best thing:

1. provide native IPv6 to customers
2. setup your own tunnelservice or if you think people won't use your
tunnelservice, setup relays

The more IPv6 the accessprovider provides the bettter the results.
Native or the closer the transition point the better.

Atleast that is the theory. :-)
