Clearly any conference interface should provide a single set of session and activity information. A useful feature of these applications is the ability to ``mute" (or hide or whatever) the local playout of a remote participant. Again, this should be possible from a single interface. Thus the conference control scheme should provide local inter-application communication, allowing the display of session information, and the selective muting of participants.
Taking this to its logical conclusion, the applications should only provide media specific features (such as volume or brightness controls), and all the rest of the conference control features should be provided through a conference control application.
