Here’s a snippet of the constructor, and the send() function…

private var _remotingChannel:Channel;
private var _svc:RemoteObject = new RemoteObject();

public function RemoteFactoryLocator()
{
   _remotingChannel = new AMFChannel("my-cfamf", "http://" + _appParams.httpHost + "/flex2gateway/");
   _remotingAMFChannelSet.addChannel(_remotingChannel);

   _svc.channelSet = _remotingAMFChannelSet;
   _svc.destination = _appParams.destination;
   _svc.source = _appParams.remotingService;
}

public function send(eventName:String, eventData:Object, responder:IResponder):AsyncToken
{
   var token:AsyncToken = _svc.invokeEvent(eventName, eventData);
   token.addResponder(responder);
   return token;
}
