How to implement a Room Mode Multiplayer Game code structure.

I am trying to seperate players into different room by setting them a difenent networView.group id just like this:

     function OnPlayerConnected(p:NetworkPlayer) {
       var n:int = Network.connections.length;
       if ((n%2) == 1) { // simply divide into 2 room(room id is 3 and 4).
         Network.SetReceivingEnabled(p, 4, false);
         Network.SetSendingEnabled(p, 4, false);
         networkView.RPC("SetGroup", player, 3);
         // the odd player will be in room 3 and not receive room 4's message
       } else {
         Network.SetReceivingEnabled(p, 3, false);
         Network.SetSendingEnabled(p, 3, false);
         networkView.RPC("SetGroup", player, 4);
         // the even player will be in room 4 and not receive room 3's message
       }
     }
     @RPC
     function SetGroup(group:int) {
       myRoomGroup = group;
     }
     function OnGUI() { // client
       if (Network.isClient) {
         if (GUILayout.Button("spawn")) {
           Network.Instantiate(prefabTest, Vector3.zero, Quaternion.identity, myRoomGroup);
         }
       }
     }

Ok, that is the main code above, and the situation is like this: There are Server, Client1, Client2, Client3 for this test.

     Server.start();
     Client1.connect(); // in room 3
     Client2.connect(); // in room 4
     Client1.click("spawn");
       // PrefabTest.spawned at Client1 and at Server.
       // PrefabTest doing not instantiated in Client2 is what I want as I just want
       // seperate Client1 and Client2 to different room. And there meesage won't send
       // to each or received from, so now it runs well.
     Client2.click("spawn");
       // PrefabTest.spawned at Client2 and at Server.
       // So this is also right for my purpose.
     Client3.connect(); // in room 3
       // Client1.prefabTest is synchronized to Client3(yes, i want it);
       // Client2.prefabTest is also synchronized to Client3(oh no...);
 

The problem is that the Client2.prefabTest should not be instantiated to Client3 as that is not I want. And the reason is that the buffered-RPC(Network.Instaiated) is invoked when a player connected and before Server.OnPlayerOnnected is called, so my code is a little later than the auto-synchronization, so the problem occurred.

As trying useing the NetworkView with a same group id insteading of the Network.Instantiate for synchonizing GameObject, the Synchronization is always lanuched from the server to client since the networkView.owner(0) is alway the server.

I have try thinking of many way to implement a room mode for multiplayer game by using Network System, but I think I am going in a wrong way (:3|L)_. So what is the correct way to implement Room mode using unity's Network System? Many thank for any replay :) .
