Well, Section 3.1 of draft-ietf-v6ops-ipv6-cpe-router-09
seems to acknowledge the existence of current IPv4 End-user
networks, and that: "It is not expected that an end-user
will change their existing network topology with the
introduction of IPv6".

It seems therefore that there will be a class of end
user networks that would benefit from an intra-site
IPv6/IPv4 transition technology.

The host would prefer native IPv6 over ISATAP. But,
not all home/soho networks are set up for native IPv6.

Thanks - Fred
