Re: [rtcweb] I-D Action: draft-ietf-rtcweb-overview-00.txt

Speaking with editor hat on:

Unless someone else chimes in, I am not going to act on these requests.

I regard the tying of "real-time" to "hundreds of milliseconds" as 
important - I have been in discussions where people have started arguing 
about single-millisecond delays and in discussions where people argue 
that "lag is not important as long as delivery occurs at a constant 
rate" - both are, to my mind, inappropriate and/or irrelevant for our 
use cases.

With regard to "in a given time scale between known ahead-of-time (AOT) 
rate and known just-in-time (JIT) rate", I don't understand its intention.
