He he, really interesting post x-trix-c, and you are feeling something that is near my projects. I currently don't have the time to write and develop a correct answer to your message.
But you point the right thing
I will answer to you in a big post during this summer, it will probably be called something near :
"
architecture for a peer to peer MMORPG based on the GPL Quake2 engine". And it will be the base of the WorldServer version 0.4
stay tuned
PS : I'm currently a little bored by coding, it's why I have reported my attention to content, like the use of the 3D tool
Blender, but for
Quake purposeof course !
