I need advice on what is needed to write a multi-player Java Applet game. A recommended tutorial would be sufficent.

I am new to Java but not a complete beginner but I need an understanding on how two people at different locations would use the same Applet to play the same game. I presume that someone needs to be a host or start the game and then other players can join in. This may be wrong I don't know. Any help would be gratefully received.

James :-)
