and idea you could try would be to make some servers more public, such as a in-game forum, where people can talk to each other, and trace each other, it'll also spark some player v player action since someone might disagree with someone
there should also be servers that collect different software, though it could only be defensive software, since in real life you can't go download a crack anywhere, but you can find almost unlimited numbers of firewalls and the like
fire walls should also stack, since you'd have to defeat each firewall separately
i think this would make the game more entertaining and make it so players communicate more, which again, makes it funner, and also provides another way for someone to be sloppy and get cracked!
