Multiplayer Animation Plugin

So I’m trying to write a plugin that will make animating a scene in my movie very fast, [and fun]. I would make the scene into a game that I and a few of my friends would play and it would record what happens and use it in my movie. I’ve started work on my plugin, but it’s not going too well so far. Since I’m going to use the BGE, I’ve write everything in python scripts. Everything is in a single .blend file too.
The clients send object move updates to the server, but the other clients can’t recieve it… I’m sure this is a very inefficent way of doing this, but I can’t think of any other way… Help Please?
