Comm'd today, and was thinking that it would be awesome if as a cool micro trick, the Comm could initiate a distress beacon, and then manually click on a specific marine to override teleporting that specific player. Often, commanders want to beacon all their players to one place for an assault, but really want one player to sneak around back and cap RTs or do something sinister. If that player were already in the right place at the right time, you don't necessarily want to interrupt them on their mission.
Or, when a distress beacon is triggered, put a little clickable X over their head to toggle whether they get teleported in 3 seconds, or whatever. It could lead to some mad depth for Marine commanders.
