SAS, jim, Shy & D49(your P.S.) - it seems we're all very much singing of the same hymn sheet. Once upon a time it was called common sense, but some people seem to require a nanny all their lives, while others get on with it and remember that we continue learning, loooooooooong after we've left school!
jim -that would appear to be an eminently sensible use of a fellow professional, who will likely absorb both the skills and raison d'etre very quickly, just before reverting to the primary job s/he's been flown there for.
Hurrah for common sense
