Fortunately IPv6 does not require 'change all network devices' as its
deployment model. It will work fine by treating the existing IPv4
Internet as a layer-2 multi-access media (which happens to have a well
recognized 20 byte frame header) like IPv4 does with Frame Relay. Refer
to draft-ietf-ngtrans-teredo-05.txt as a way to push the NAT traversal
problem out of your space, so you can focus on simply making end-to-end
IPsec work well. There is no reason to waste the time of this WG on an
experiment that escaped from the lab and went very wrong...
