uLink + uLobby + uZone2 doubts (^.~)

Where do fit the uLobby?

I'm facing many difficulties in understanding and developing my application using the uzone, for example material is very limited and answers from oficial forum as well.

I need to start new instances of my server dynamically.
I am using the example of the website, but it is all done manually.

I believe the solution is in use uLobby. Correct?
Looking at my diagram, I would like to know the following:
Where do fit the uLobby?

 

Watching all the examples available in webSite, I believe that my second diagram is correct.
did right?

uLobb -> connected to uZone Master

Code (CSharp):

1. uLobby.Lobby.AddListener(this);
2.   uZone.InstanceManager.Initialize();
3.  
4.   uZone.ConnectRequest connectionRequest = uZone.InstanceManager.Connect(uZoneHost, uZonePort);
5.   yield return connectionRequest.WaitUntilDone();
6.  
7.   if (connectionRequest.hasFailed)
8.   {
9.   Debug.LogError(connectionRequest.GetErrorString());
10.   yield break;
11.   }
12.   else
13.   {
14.   Debug.Log("Connected to uZone");
15.   uLobby.Lobby.InitializeLobby(maxLobbyConnections, lobbyPort);
16.   }

Clients -> connects to the lobby, and the lobby waiting return a valid server for it to connect.

Did Right?
