[Red5] Getting a List of Users?

[abogartz makaimedia.com]

Hi there, I've gotten Red 5 working, and so now I'm trying to delve into
the various functions.  

I've copied over the following connect method:

private ClientManager clientMgr = new ClientManager("clientlist",
false);

	public boolean connect(IConnection conn, IScope scope, Object[]
params) {
		// Check if the user passed valid parameters.
		if (params == null || params.length == 0) {
			log.debug("Client didn't pass a username.");
			// NOTE: "rejectClient" terminates the execution
of the current method!
			rejectClient("No username passed.");
		}

		// Call original method of parent class.
		if (!super.connect(conn, scope, params)) {
			return false;
		}

		String username = params[0].toString();
		String uid = conn.getClient().getId();
		if (log.isDebugEnabled()) {
			log.debug("Client \"" + username + "\" (" + uid
+ ") connected.");
		}
		// Register the user in the shared object.
		clientMgr.addClient(scope, username, uid);
		// Notify client about unique id.
		ServiceUtils.invokeOnConnection(conn, "setClientID",
				new Object[] { uid });
		return true;
	}

What I'd like to do is that whenever someone connects, everyone in the
room gets an updated list of users.  How might I handle that?  I assume
I iterate through some list, but I'm not sure.  Any help would be
appreciated!

Thanks!
