Good!  I need to think on it more too.  It's much more like your first
495 stab, which indeed had many nice properties.  Nobody here gives a
shit about the interzone by-magic operations, so I'm happy to
sacrifice damn near anything in those ;-)

FYI, I'm most concerned about how glibly I "sold" the idea that it
really does solve the hash problem.  It seems obvious to me that it
does, but ... hash problems have a way of popping up in unexpected
ways in unconsidered contexts :-(
