I wish I could choose two options.

I say No to PC because:

1. It'll never be done.
2. It isn't needed.
3. It would probably be easy to abuse and hard to apply with what you say.

Ex; Player A and Player B trade a gun back and forth for their combined money to raise the price extremely high. A + B then sell the gun to Player C for the new price, claiming it's amazing, and split the money. (Similar to when people I know would try to sell things and they wanted me to answer 'PC' masses with false prices)
Ex2; Player A sells a gun to Player B for a different gun + cash, how would it be calculated..?

However I would approve this idea for IPhone because:

1. The economy is new and they might be able to apply/control it.
2. They might be able to make it, since they have staff [that actually login].
3. [Most of] the players are new to 'Era' and haven't been around merchanting for years with a small populace of ~100. So the system could be of some use and help players.
