I've been looking into the P2P support in Flash 10, using Adobe Stratus service. I have successfully been able to send data from one user to another, put my problem is that I haven't figured out how to send data back in some easy way (or as some kind of response to the first call).

What I'm currently doing;

1. First set up a connection with Stratus service

   nc = new NetConnection();
   nc.addEventListener(NetStatusEvent.NET_STATUS, ncStatusHandler);
   nc.connect(APPLICATION_URL + DEVELOPER_KEY);
   

2. On the "server" side I do:

   sendStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS);
   sendStream.addEventListener(NetStatusEvent.NET_STATUS, sendStreamHandler);
   sendStream.publish("file");
   

   And on the "client" side:

   // remoteFileID.text is manually copied by the user from the server (which is nc.nearID).
   recvStream = new NetStream(nc, remoteFileID.text); 
   recvStream.client = this;
   recvStream.addEventListener(NetStatusEvent.NET_STATUS, recvStreamHandler);
   recvStream.play("file");
   

3. Then I call a remote function on the client:

   ...
   sendStream.send("aRemoteFunction", parameterData);
   ...
   

4. Now my problem; I want to do the same from the client to the server, to notify that everything went well, or something failed. From what I understand, I will have to setup a new NetStream from the client to the server (i.e publish on the client and play on the server). But to accomplish this, the server need to know the nc.nearID on the client.

   Is it possible to get that ID without forcing the user to manually copy it from the client to server? Or, is there an easier way for the client to talk back to the server that I am missing?
