+1 to Ned. I can't see why this draft seems to make some people
go defensive - it isn't saying "IPv4 is evil" or anything silly
like that, it's just saying "IPv6 is the future".

RFC1122v6 is another matter entirely. We clearly aren't ready
for it yet, but draft-ietf-6man-node-req-bis is a step on the way.

Regards
