Reviewer comments:
NAME I think this is ready for review and merging .
Duplicated "without without waiting" in Section 2.1. I wish I had spotted "where a user wishes to observe or control the graphical user interface of another computer through local user interfaces" in 3.1.2 - I'd suggest saying this as "where a user wishes to observe or control the graphical user interface of another computer through user interfaces that are local to the user". I think "This may include audio from both microphone(s) and/or cameras, or may include "screen sharing" or inclusion of other content such as slide, document, or video presentation" in 3.1.3 might need adjusting. Doesn't this need to say, "This may include audio from microphone(s) and/or cameras, and may include "screen sharing" or inclusion of other content such as slide, document, or video presentation"? (Also, we named everything except video as a media type, but if we're changing that paragraph anyway, we can add video as well) in 3.2, I had difficulty parsing "As this has a much larger total number of participants - as many as Live Media Streaming , but with the bi-directionality of conferencing, this should be considered a "hybrid"." I wasn't sure "much larger than what?" Is this intended to say something like "This use case can have an audience as large as Live Media Streaming as described in Section 3.3.3, but also relies on the interactivity and bi-directionality of conferencing as in Video Conferencing as described in Section 3.1.3. For this reason, this type of use case can be considered a "hybrid". (if we're forward-referencing section 3.3.3 in Section 3.2, this might be clearer if we swapped the order of Sections 3.2 and 3.3) In section 3.3.1, are there any non-hypothetical media types beyond "audio and/or video"? In Section 3.3.3, I asked you to distinguish between the live edge and the trailing edge (thank you for that), but I didn't realize that "either because the local player falls behind edge" was now unqualified. Is this "either because the local player falls behind the live edge**"? In 4.9.1, "this is infeasible in many use cases where provisioning of client TLS certificates is unsupported or infeasible." has two "infeasible"s. Perhaps one could be "impractical"? Your choice which, of course.
In submitting the -00 working group version, we tripped over an incompatibility between XML2RFC and google-i18n-address 3.0.0. The details are at URL and at URL I took the shortcut of removing the country: attributes for the authors in -00, but (per the comments on those issues, a version of XML2RFC that has been deployed, so we can add our country attributes back when we're fixing the nits identified in this issue. And NAME says it's "The Netherlands", but I'll let NAME and NAME wrestile that one out ... :zippermouthface:
