A forward:
"PvE" in the context of DayZ will refer to grouping all human players onto a single team, and then disabling friendly fire - effectively preventing one player from shooting another player.
While I'm certain no-one would accept a "PvE" mode in a public server context, a lot of my friends (myself included) want to see a "PvE" mode added to the game where we can essentially group all players onto one team and disable friendly fire - effectively removing the threat of being shot at by random people. While I'm sure the overwhelming majority of people play DayZ for it's stellar PvP aspects, many of us are quite content to enjoy the game's military simulator ballistics and wide open terrain as a game unto themselves.
It would be a relatively simple thing to implement, and give those of us who do not wish to PvP a place to go so we can enjoy the games many other enjoyable aspects.
