I thought making a game was going to be easy but the network part is starting to be a little nightmare and a challenge.

here is PDF that might give me some answers (2006) network and this website (2010) http://vast.sourceforge.net/

Jmonkey has a networking built in so i will have to look into it a little more. here is a tutorial

This is a good document on MMOG Survey on Network Game Cheats and P2P Solutions1

To create a 3D you also need a network to play on. I think I will use Jxta is open source and p2p so I don’t need a server.
