Hi Magnus, We just published version -10. See below for some comments.

The requirement on all caps ones I am very divided about. I do have a preference for unmodified boilerplate, this as I otherwise have to explain in the write-up the ID-nit. Fixed. > > 6.

Thus affecting the TURN channel allocation algorithm in the client implementations, at least when used in combination of muxing.

So please add that in header, abstract and introduction. Based on our understanding and looking at other RFCs, just updating an IANA registry does not imply a update to the core specification, so we did not made that change. > > 7.

I guess it one that has to be accepted in this case. I suggest that you move it to the normative references. We are keeping it informative for now, but we will forward the discussion with the AD to the mailing-list as requested. -- Marc Petit-Huguenin Email: marc@petit-huguenin.org Blog: http://blog.marc.petit-huguenin.org Profile: http://www.linkedin.com/in/petithug
