I’m not quitting :) but at the moment, I don’t have as much to add to the group effort as I’m less far along, and it’s better to conservatively wait out any possible churn as my system is less amenable to rapid prototyping.

The current draft is implementable and there does appear to be considerable interest in going forward with it to see how it goes. 

“Back to the drawing board” might have been a little strong, heh, I just meant the framing layer and the protocol-wide state machine that tracks header blocks are pretty fundamental.

As a newbie, this group has always responded nicely to my ideas, even if I don’t have much “push.” Things currently seem to be going in a good direction. The immediate effort with headers and framing is for minimizing RAM and cycles per stream, and that’s the bread and butter of the whole operation.

Massive headers I find worrisome, only because they are already theoretically supported by HTTP/1 but implementations universally impose limitations. The existing practice needs more emphasis. But, this too seems to be getting addressed currently.
