private var serverWebcamURL:String = \"rtmp://myserverIP/live\";
private var serverChatURL:String = \"rtmp://myserverIP/multicast/chat\";

var connection:NetConnection = new NetConnection();
connection.connect(yourServerIp);
var stream:NetStream = new NetStream(connection);
stream.receiveAudio(true);
stream.receiveVideo(true);
stream.attachAudio(Microphone.getMicrophone());
stream.attachVideo(Camera.getCamera());
stream.client = this; // Yous should look this up.  This is for client to client communication using a \'handler\' within this class
stream.publish(\'media\');
stream.play(\'media\');

private function message(someMessage:String):void
{
// do something
}

stream.send(\'message\', yourMessage);
