you have been saying that for years.  and i understand your point.  what
i have never understood is *how* you can tell how things 'should' be.

so the current sidr proposals are for what we *know how to do.*  they
are not perfect, but they are a radical improvement on the current
state.

i am very open to clue on how to rigorously define how things 'should'
be, especially if it is rigorously testable given real world
constraints.
