I would put all of the NPCs that you use into seperate text files for the stuff. Put like a bank item in the trading house, then, if they say "trade <npchere> spot1" and the other person says "trade <npchere> spot2". Then, make it so they have to accept then have it destroy it in the players weapon list and use putnpc to put it in front of them. With the bank use something like "<ammounthere> for spot1" or vica versa. Then it drops the ammount into spot 1 or 2. It may be laggy, but, it should work. As for the trading item itself, it would be kind of hard, because, if the person "lagged" and someone else came by, they both would get it.
