Any alternative beyond the simple and obvious encap/decap that routers have used for decades is already too much IMHO, we certainly don't need a 3rd or 4th method.

Sorry that you see it that way.

The interim meeting has been useful in that objectives of present parties were clarified better than ever before.
Standardization is, and has always been, a process in which understanding each other, and finding ways to accommodate all valid concerns, are been key to success.
That's what I have been working for: good standardization. 

Would you please indicate what you personally challenge in this:
a) One standard is better than two.
b) Maintaining network transparency to IPv4 packets is a useful feature
c) Being able to apply IPv6 O&M tools to IPv4 traffic, e.g. with ACLs, is a useful feature
d) Encapsulation has b) but not c)
e) Double translation has c) but not b)
f) 4rd-U has both b) and c)
