Just a quick note here, since this is one of the more confusing  
aspects of appconference:
To get VAD-based video switching  working, your clients need to use  
DTX (i.e. stop sending audio packets when there is no voice  
activity).  While it is possible to implement a full VAD solution in  
appconference (the relevant code is there), VAD is quite CPU- 
intensive, so there are advantages to offloading this to the clients.
