Networking initial questions

Hi,

I've run into some problems with my network game-architecture. To prevent further unforeseen issues I have a few question. This is the situation I would like to code:

• I have an initial level for the player to choose to be either server or client. The server may choose a map. This map is loaded on his machine an all those clients that connect to him
• On the map I have the standard "spawnscript" to Network.Instantiate a player prefab for each person playind the game

Here are the questions

1. Is there a problem with the connection if server and client currently have different levels ? The server has already loaded the map but the client still needs an RPC to load that level.
2. How can I receive the RPC to load the level ? So far I've understood that RPCs are called within one script. It "talks to itself" to update its status.
3. Let's say there is no way to do the two things above. Then I would let each player choose a map and the "connect" script would be added to the map. Therefore after starting the game the player sees a GUI with different levels. After selecting one the level is loaded and he's asked wether he'd like to be player or client. Now my question: Player A chooses map 1 and starts as server, player B selects map 2 and tries to connect to A. What happens ?
4. If I choose the initial aproach, what events can I use to spawn players? Because the server is established in the startlevel I can't use "OnServerInitialized" to spawn the server's player prefab on the map. I found an event called "OnNetworkLoadedLevel" but I can't find any documentation.
