Looking for an MMO that has a Good Trading System

[bacobit]

One of my favorite things about early Runescape was that you could set up a production line with your friends (ex. Someone fishes for lobsters, next person cooks them, and someone sells them outside a boss's lair or something.) Is there something like this available on iOS? I know that's sorta specific, but as long as it has trading I think it'll do just fine. Thank you reading and I hope you can help.

Albion Online. It's now listed listed in the upcoming iPad games and looks very promising for meaningful player production and trade.

Trading system? Well Order & Chaos has an auction house and the ability for individual players to trade.

Also a great MMO
