Thread's gettin off track.
Spectator mode is a good idea in general. It would be nice to see a list of "matches in progress" that you could drop in on and watch live play. When watching live play, it should be just like waiting for your partner in your foursome. You wouldn't be able see the meter, the exact club being used and (for this to work) no aim either. You would only see the ball, ball flight and where it lands.
The problem currently is that the game can barely handle 4 people connected. Add spectators and that's a recipe for laggy meters, disconnections and general slow play. In time perhaps.
