The tittle of this thread got me excited. It turned out to be a major let down.
But on topic, coaching will happen, whether it's allowed or not. Teams will use every means possible to get that little edge, whether it's sliding a certain way to wipe off a hit or having someone on the side lines following players. The only way I can really see it being stopped is if the spectator areas are pulled far enough back from the fields that it wouldn't make a difference. But then this would suck for the spectators. But then again think about old school Toulouse when they used to play in the football stadium. That was an amazing atmosphere and the fans were removed from the sidelines.
