Yep, fascinating read. I'm closing this one down, nevertheless, as another Ppruner has posted the entire article just shortly after yours. We normally work on the principle of first-in when this happens, but in this case, to avoid duplication on this topic, I'll leave the other thread open.
Top post, mind you. I'm sure you won't mind this wee bit of housekeeping...
