That sounds like a very interesting remedy, having an observer present would probably quell the cheating even if they are not well sighted for a particular line. This would be an interesting area to explore how it would work out. So the impartial observer(s) can't make calls or correct them--but can comment on them--"They just cheated us!"--"No comment, but philosophically you may be correct, perhaps cheat them back, you don't go to hell for cheating in tennis (that we know of), good luck."
