Could be developed a DMFlag making single pickups, (ammo and/or inventory) to be collected by everybody, and then despawn? wich can't be picked up twice by the same player but just 1 time per person. maybe dsappearing too for who already did it and keeping it in the map for who still has to. something like that, hope I've explained well

I think I already have seen this somewhere, maybe in duke3d or doomsday I'm not sure.. was quite long time ago.
Thank you
