Hmm... I just thought about file structure. If you want to start 2 identical servers on the same versions, with custom maps, you will have a problem - fs_homepath (.callofduty2 folder). With the same fs_game and the same fs_homepath you will have problems with Library (2 maps in server folder - users will download both, even they don't need one of them).

So, let's think about it - how to avoid it, any opinions?

Yes, we can create new fs_homepath for each server, but it isn't correct, I think... We can also ask about count of servers with the same fs_game... yeah, maybe it's the best way here, but I also want to hear some killtube opinions.
