PvP and Penalty for Death

I saw the game design document on the wiki and I noticed that under stealing and looting it said there would be player run justice, and I wondered if you had plans for open pvp? All games I've played that had this system had open pvp and people who killed other players without a reason got a bounty or something similar. I personally like it but it's your call of course, I'm just curious.

Also what will be the penalty for dying in BS?
