Thinking about it, for the sake of the PS3 users, I think a party voice chat option would be fine for SE to implement. Simply allowing you to communicate via voice only with those that are in your party solves most all problems. Yeah behest voice chat would suck but it's part of how things are. A mute player option also isn't too far fetched, especially for consoles. Honestly these days it's more common for a console user to have a mic than a keyboard attached.
