If the IETF process can't converge to something we can ship after all this time, based on experience with running code both before and during the process, there isn't a lot of point of discussing it in this forum. Redoing the base framing at this point is fairly close to declaring IETF fail at this stage. I would hope we wouldn't do that. different pov's will continue to crop up and the wg has decided to have an extension mechanism available to try some of them out among their own advocates. (as we know, I'm not a huge fan of that - but there it is.) This will get runtime experience with them. Changing framing is certainly something that can be done this way. It takes a RTT to take effect but the swtichover can certainly take place mid stream among consensual peers. (so it need not add a rtt of overall latency). it would be interesting to get experience with an extension that did this and bundled a MAX_CONCURRENT of 1 semantic (or requirement) with it because you can't really expect to mux successfully in such an environment. At that point the value of running h2 is kind of questionable - h2 fundamentally needs mux and priority. And that's why I think this whole path is the wrong thing to do. I'm looking at a spdy trace right now that sends huge frames because it was convenient for the developer to do so - and priority doesn't work at all as a consequence. That's real feedback that improved h2 over spdy. -P
