[BEHAVE] Applicability statements for NAT66

[Fred Baker <[e-mail]>]

One thing that bothers me in the NAT66 document is the commentary  
about recommended utility. I am of the opinion that there are at least  
two obvious use cases for IPv6/IPv6 NAT: business-to-business ULA-to- 
ULA exchanges with the intention of topology hiding (see http://tools.ietf.org/id/draft-baker-v6ops-b2b-private-routing 
  for a discussion), and GSE. As such, while a subset of the IETF has  
a strong aversion to translation in general and IPv6/IPv6 translation  
in specific, a proper applicability statement would recognize the use  
cases.

Also, IETF applicability statements are generally separate from the  
statement of the algorithm they comment on. I list a few of these at  
the end of this note.

As such, I would strongly recommend that any applicability statement  
be a companion document to NAT66 as opposed to having a half-baked  
statement in the interior of the document.
