I've wondered about this as well. It would seem like a really good place to put mini games where the social area of Destiny is. Buts it hard to say. It might distract players from the main game and Bungie might not want that.
I think that would be a pretty cool aspect to put into the game. Bungie has talked about non combat public events so it is very possible that they would do something like that somehow incorporated into the game.
