hi fellas, I'm glad to see you've managed to connect and enjoy cfs2 multi-player.
I would strongly recommend you connect to each other via skype or some other secure messaging service to exchange critical info, I do not think it wise to exchange IP addresses, operating system info etc over a public forum such as SOH.
I see you are considering adding AI targets. You can do this by using a thing called brunhost.
It's a program that hosts a CFS 1 or 2 multiplayer session and injects data for AI targets that all real players will see in the same location, as far as your CFS2 is concerned the brunhost AI is just other real players. Brunhost requires a mission script that is very similar to CFS1/2 mission file but of course it must be edited by hand.
Now comes the question where can brunhost be found? after a quick google search it seems to be lost on the net , but I have it, so send me a private message with your email and I'll forward you a zip.
