[gameprogrammer] Multiplayer networking advice

["Taylor Peterson" <assbone@gmail.com>]

Hello everyone~

I'm not a very frequent poster, but I do read a lot.  I was looking for some advice on networking a game as I'm very new in that area.
In my little network game players will be able to make their own little avatars (in what ever image editing program) and upload them somewhere (like imageshack or photobucket)  and paste the url to those images into a config file.  And they'll be able to interact with others and what not in a little world.  

My problem with this is, I've never done a game where more than two people connected to each other and play (they'll have to connect to a server now).  So I'm confused as to how I could draw all of them on screen and keep it updated.  

Here's what I've come up with in my own inexperienced mind:

Please critique it, or tell me if it's even posible.  

Thanks,
Taylor
