I agree on the whole with what you are saying.

If some one wants to help these carburetor stricken third world countries then they should invent a dirt cheap wide band O2 meter for tuning.
When I started using a wide band 02 meter and the advanced 100+ piece Edelbrock tuning rod, jet and spring set on my Camaro to tune its Edelbrock 650 with vacuum secondaries it was almost as good as fuel injection.
Its amazing what you can do with a carburetor when you go from just guessing to actually seeing whats going on and having the parts to do something about it.

I say to be able to do any successful fuel vaporing you have to master the carburetor or fuel injection on the vehicle to be experimented on first.
But, there is value in the so called "miracle devices" if they have a basis in science. I had previously linked to the Smokey System and the Clackamas Vapor Carb. Old Mech linked to the Transonic Injector technology. These are not simple vapor carbs, but they point to the continued development in fuel systems. After you have improved fuel feed with carbs, injectors, and now direct injection and applied it to an over expanded engine, a designer needs to start looking for more efficiency and emissions advantage. The goverment has MANDATED 50+ MPG cars in 10 years. Does your "well tunded carb" have the ability to meet the requirements? I don't think so.

So it is with Ecomodders. We each have our interests and goals but fuel economy is what ties us together, and some of us are much more capable in the areas of engine development and controls. But, just like the manufacturers pushing the edge, engine development is going to be on the edge for most Ecomodders.

But, I do agree whole heartedly with you - you have to know what you are doing and have the tools to perform measurement and control.
