Granted that the technology is feasible (and, FWIW, I believe it) how to address the political/social side of it to actually "get 'er done!"?

Technically, your stance or proposals are a political extreme, eh?

FWIW, and apologies if this seems way out of left field, there is a kind of psychological algorithm called "Core Transformation Process". It operates between a guide and a single subject, in a therapeutic setting, to resolve and transform personal issues. Now I suspect, although I haven't tried it, that a variation designed to work with two subjects simultaneously (or alternating, or something) could work really well as a kind of negotiation or conflict-resolution process.

The thing is, something like that is even further out sociopolitically than your technology-saves-the-day proposals (which, again, I am all in favor of, FWIW.)
