I saw someone earlier talking about implementing a player based economy, or at least thoughts on how it would be done. You could kind of easily do this now: If someone created a new "Faction" that was all around trading. I don't know, I personally wouldn't join but it seems like an interesting idea. You could have multiple jobs inside the trading co., from gathering things to sell, repairing, storing (because im assuming storage would be the biggest issue) and carivaning the gear to established store areas. since enemies re spawn you can pretty easily get armor, weapons, aid... etc. And if you have stores in places that the npc vendors were removed like in primm the biggest problem would be storage and organisation.
