Rick, Somebody suggested Teredo instead. The problem with Teredo is that it uses a generic prefix and an anycast IPv4 address. Thus it has some operational problems (less serious than 6to4, but still...). A variant of Teredo that can use a provider-specific prefix and a unicast IPv4 address would surely do for the embedded systems market. But we haven't found enough interest in the IETF for that approach. See draft-carpenter-softwire-sample-00.txt, draft-lee-softwire-6rd-udp-02.txt and draft-despres-6a44-00.txt for the historic trail.
