Thanks Andrew, I am happy to see a survey draft, I never seen one
before in IETF, however, if there was a survey done before in IETF, it
will be interesting to mention that if you think necessary related.

Yes that was my aim, thanks,

ok, if described in the document, and how were they selected, is it on

Ok, the WG needs information, but if I still remember, the document
does not state/define such need to match the survey.

The questionnaire method has advantages and disadvantages, so if on
section mentions the result validity in linked to method, I think the
reader will know how much he can depend on such results.

my language may not be perfect, but I agree that amending it to show
survey method and method of result collection.

I think that is an important information, because the WG is part of
the community, not sure if you have service providers respondent which
are joined in the WG, if so then that information is important also,
even if there is no respondant in the WG participating mentioning that
is important also.

I thought the subject is implementation and interoperability of such
technology, therefore, security is always important subject for users.
However, if the survey does not want the security, mentioning that in
one section will show that it was out of scope (if I remember the
security related to implementations of users was not mentioned as out
of scope).

In section 2 you mention many things that you have given to
respondants but that is not a result, what you give is a survey
method, but the respondants actions is the result. So I suggest to
take any information of your survey from the result section 2.

Thanking you,
