Well, well. People mix and people misunderstand and misjudge each other.
It's the way of things with people. I just needed to tell you how it all
looked from my side.  So are we done with that?  I certainly hope so.

I'm quite well aware by now that there is no one-sentence answer to my
original question, if there's any coherent answer at all. Them's the
breaks. Live with it or live without it, it doesn't care.

I do appreciate the education I've gotten on this thread about the
issues involved. But I rather imagine that near term anyway, I'll only
be pondering it now and then, and maybe poking around a bit. Who knows,
maybe I'll eventually invent the solution and make my first million
dollars from it.  haha, yeah right.

So it goes.
