[Nsaas] Existing work, other things

[Melinda Shore <[e-mail]>]

I was a little (okay, a lot) surprised to see this work
proposed without referencing prior IETF work in this space,
including (but not limited to) midcom, nsis, and pcp.
Ideally any new work proposed on this topic would include
an explanation of why it would succeed where previous
efforts haven't.  It's certainly possible that this might
succeed where others have failed, but some explanation
of why its proponents think this time things are different
would be helpful.  Some discussion of what distinguishes
"security" from other service functions would also be useful.

Also, the open source vs. standards discussion is overly
argumentative and likely to produce more heat than light,
and fails to acknowledge the complementary nature of the
two types of effort.  We certainly do not need more
unimplemented standards (see previous paragraph).
