The ACE mod has a weight system that even effects your stamina. It most certainly could be implemented into DayZ, and as for ArmA 3 you all must have missed the part where its going to support java :) Huge modding potential there.

That would be very cool.

I think a squad of AI would easily get overwhelmed by zombies, and their bodies could be made to disappear quicker than normal. I don't mean hordes of AI roaming around, I mean like a 5 or 6 man SF team. As for the assaults on towns, again it could be in relatively small numbers (platoon size), with the units despawning after a certain amount of time if they aren't dead already.

What I'm thinking is squads (or a squad) of AI units such as Spetznas roaming the map at random. They'd be hostile to all players but the upside is that if you encounter them and are able to take them out, you can loot their sweet gear. Random events such as AI airborne assaults on different towns would be pretty sweet too. Don't know how well the servers would handle these additions though judging by the current state of things :P But it would be a nice feature to see some day.

I have only done it to escape zombies glitching through walls or stupid things like that, but never in a fight with another player. I do agree however that there needs to be something in place to stop it completely.
