This might be more of a suggestion for WebRTC, but can we get a local mute? Right now the behavior is inconsistent when people have only a microphone vs having a webcam (you can mute one but not the other), and local echoes are super-annoying if two/three people are playing from one location. Edit: Google Hangouts only has global mute (if person A mutes person B, person C can't hear B either). I'd like local mutes, where if A and B are in the same house, they can mute each other, but person C can still hear both.
