It's true that addStream/removeStream won't perform any ICE activities in the multiplexing case, but it is convenient, from an implementation point of view, that the spec defines a separation between an internal component owned by PeerConnection responsible for performing ICE and protocol-related operations, e.g. in the constructor, and the PeerConnection JavaScript object. But I agree that ICE Agent may not be the best name (we call it PeerHandler in our implementation in lack of a better name).
