I think it's really important  to distinguish between "this draft solves a
problem" and "this draft solves a problem that can't be solved already" and
"this experiment has succeed and we can promote the document to
informational or standards-track."

I think we can all agree that this draft solves a problem. I think it
solves exactly one problem: allowing sites to keep stable internal
addressing in the face of renumbering by ISPs and/or changing ISPs.

However, this problem can be addressed the way 7084 currently solves it: by
numbering the internal network with a stable ULA and hosting services on
addresses within that ULA rather than on a temporary GUA provided by the
ISP.

Problems NPTV6 does not solve:

* MHMP (although it solves some aspects)
* Internal address privacy

So I don't actually think this document does anything useful for the
Internet community. I don't mind that there is a document that describes
NPTv6, but I don't think it should be standards track or informational, and
I don't think IETF documents should normatively reference it.

Regarding experiments, at least from a scientific perspective, an
experiment needs to have a control group. If we wanted to know whether
NPTv6 solved the problem in an easier way than dual ULA/GUA, we would want
to set up an experiment where some sites continued to use IPv4, some used
NPTv6, and some used ULA/GUA. As far as I know, no such experiment has been
done, and no such comparison has been documented.

I think the presentation Paulo has just done is the most interesting, but
what we are not seeing is an answer to the question "how's it going, what
problems do you have, etc."
