Master server and problem

Hello,

If i use master server ( http://docs.unity3d.com/Documentation/Components/net-MasterServer.html ) to handle all connections and new game registery, and i wan’t to those clients communicate with master server while in game. How it happens? I want my players item drops handled in main server.

The master server is not a game server, as stated in the page you have linked in:

The master server provides a list of games that are registered with the master server, it provides the info on how to connect to those games.

Okey , that makes sense. So now i know how to handle multiple games. But now to the my question, what is best method to handle data between clients ?

Let me explaing better.

im gonna create chat channels, players connects there automaticly after login and in that chat screen there is also list of games and button to create own game.

i need save each connection to array on my server and pass chat messages and other stuff on right players on right channels when someone speaks. Same with games, but there is something i want to know, does unity have own mechanism to pass data to only players in same game ? If no , what i do?
