In my opinion this kind of document is very useful and addresses recurrent questions in this list and in the industry.  Some comments:

- I would add a recommendation on automatic TURN reconnections to handle proxies max connection timeout.

- I would clarify that scenarios in section 2 only require TURN server if both endpoints and behind that type of NAT, not if only one of them is behind it.

- In section 2.2 we could add a comment on the requirement for simultaneous-open support in case both endpoints and behind that kind of NAT/FW.

- There is a 3GPP document with a similar scope and introduces a similar taxonomy (http://www.3gpp.org/ftp/Specs/html-info/33830.htm).   I don't like the terminology in that document but I think it is worth keeping it in mind and probably referencing it.
