Answer 1

oh yeah I was a little hasty on this one sorry. I would probably have an object on the server side that tracks all users and have an attribute that denotes presenter or subscriber. something like
//intialize in onAppStart
this.adminObj = new Object();
//get user data from connection string on client side
"rtmp://192.168.1.102/someApp/someInstance","userNameVariable"
//add username in onConnect to Object
client.userName=userName;
this.userObj[client.userName]=client;
//call this from client side depending on whether the user chooses to be presenter or subscriber.
Client.prototype.setStreamID = function(userName,streamType){
this.userObj[client.userName].streamID = streamType;
//find out onDisconnect what type the client is.
//application.onDisconnect = function(oldClient)
if(application.userObj[oldClient.userName].streamID=="presenter"){
  //then either send or call the subscribers
//This is imperfect just an example of how I might go about it.........I've also have tracke FPS on the client side to see when the presenter stops presenting. to track frames per second though you need to continously poll the fps property of the netstream with either a timer or onEnter (onEnterFrame).
