In order to make it harder for people with single accounts to use the film viewer as a reconnaissance mechanism, I would like to see the AH client maintain control of all film files created during that session, until the client exits. After exiting, a player could still open them on the same or on another machine, but at least there would be a significant delay before they could use the information in the films (login, re-transit to the battle, etc.).
This is a quick-and-dirty idea, so I may have overlooked something here, but in principle the idea would seem to have merit.
