Yes, I have had sucess running an AA server for 12 people. I dont use SCX or any of the other apps that "help" you host. I found some issues with them, especially on setting up a server to rotate the maps. With a few edits to your ArmyOps.ini, installing PB and setting up your pbsvgame.cfg and registering your server IP at
www.americasarmy.com under your settings.. it's up pretty fast. I run it in my terminal.
