My goal was to get something that *works*, and I can tweak the rest of it, probably with his help.
And this is what was achieved much earlier, and made it unclear what the state of the bounty was. Obviously what I mean is not going through, but never mind then. I wasn't doubting whether his solution worked, 10 paragraph email or not.
Perhaps, I shouldn't have said "just works". But I did say I would be the final arbitrator, and what he gave me was fully satisfactory. The fact that it "worked" was the final test. Any further polishing or adaptation to my workflow will be handled by me.
