Yeah, doesn't he know it's literally impossible to solve combustion instability in large chambered liquid propellant rocket engines? They'll never build a big rocket engine,
SPACE
IS
HARD

I haven't looked in depth but I figured that if such a thing were both possible and somehow better it would have been tried at least a few times since the start of rocketry. I think your guess about combustion instability is spot on, for the same reason that chamber throat sizes can only get so great before combustion instability becomes an issue. The more space the vaporizing propellants have to fly free and spread out the less predictable their behavior.

>So if I've understood this correctly you want continuous cooling pipes (contacting each other) and a continuous interface (in contact with all of the chamber).

Yes, imagine the walls of the chamber and nozzle are pipes that run lengthwise like in the picture. These pipes pump cold fuel through them, absorbing the heat that the chamber and nozzle walls will be feeling thus keeping them cool enough to be useful structurally.

For the rest of your post, perhaps a picture would be better, its hard for me to follow your train of thought on this.
