Number of viewers of live stream

Question

Hello,
I want to display the number of viewers that are watching a
video stream on a website... I am using FMS 2, and this is the
actionscript of the flash file:
connect_pb.onRelease = function(){
if(this.label == "Start Watching"){
this.label = "Stop Watching";
nc.connect("rtmp:/livecast");
} else {
this.label = "Start Watching";
nc.close();
nc = new NetConnection();
nc.onStatus = function(info) {
createNetStream(this);
createNetStream = function(nc){
ns = new NetStream(nc);
myvid.attachVideo(ns);
ns.play(stream, -1)
(it displays the video another user is streaming through his
webcam).
How can I add the number of viewers of this video to the
flash?
Thanks.

Basically, this is the actionscript I have for the
"Broadcaster" application:
/* first create a new instance of the LoadVars object */
myVars = new LoadVars();
// call the load method to load my php page
myVars.load("hs.php");
startstop_pb.enabled = false;
connect_pb.onRelease = function(){
if(this.label == "Connect"){
this.label = "Disconnect";
nc.connect("rtmp:/livecast");
} else {
this.label = "Connect";
nc.close();
nc = new NetConnection();
nc.onStatus = function(info) {
startstop_pb.enabled = true;
createNetStream(this);
createNetStream = function(nc){
ns = new NetStream(nc);
mycam = Camera.get();
mycam.setQuality(25600, 0);
mymic = Microphone.get();
mymic.setRate(11);
ns.attachVideo(mycam);
ns.attachAudio(mymic);
myvid.attachVideo(mycam);
startstop_pb.onRelease = function(){
if (this.label == "Start Broadcast"){
this.label = "Stop Broadcast";
ns.publish(myVars.hs, "live");
} else {
this.label = "Start Broadcast";
myvid.attachVideo(null);
myvid.clear();
ns.close();
---- On the other side, a "Receiver" application displays the
stream that has been published.
How do I display the number of viewers, or the number of
"receivers" subscribed to the published stream?
(example:
http://www.ustream.tv - they use
FMS2).
