I've been thinking recently that something like an OpenJazz2 is perhaps our only solution to the mass-hacking that is taking place. Jazz2 is vulnerable to memory and packet editing, which allows for some pretty cool tweaks, but also to a lot of cheating. The problem is, ofcourse, that an OpenJazz2 would need a large amount of time and a few programmers who know what they're doing. And I doubt anyone would be willing to invest so much time in it.
