I kinda thought they were using something like this. I figured that, given the close relationship between the DayZ developers and the Arma 2 developers, they could just ask for something like this to be included in the next Arma 2 patch. I can't see any reason why this would compromise Arma 2 in any way. That's a good point about scripting language vulnerabilities, I forgot that this is just a mod (due to it's popularity). I agree that my suggestion is not the best solution to this problem, a disconnect timer is the best solution. I think I heard this idea somewhere else, but rather than players crouching when they log out; they should be forced to stand for 5-10 seconds. That would force players to log out in safer, less infested, places.
