I'm thinking about it, too, Lutra. Not very effectively, admittedly , seeing as I'm feeling rather washed out, ATM. But I guess that question will keep awhile? And a few dozen half-brains are allegedly better than one.
I think that question should have it's own thread. Then we can let it percolate awhile without fear of it getting lost in the middle of this gigantic thread.
(Ooh a bit of common-sense manages to peep throgh the brain fog, and wave.
At least it seems that way to me.)
