Real-time mineral trading economy

I took a look at the mineral trade terminal and an idea struck me. Seeing how every mineral has the same fixed buying/selling price, what if instead the devs implemented a real-time economy based on what other players around the world are buying and selling?

Each mineral would start off with a base price of 100 creds per piece. The more players buy a certain mineral, the more the price hikes up, and the opposite would be true for selling. Kind of like a mini Steam market of sorts. A graph of price history would be cool too. This way, prices at the terminal woud be far more realistic, and would make the trade terminal a whole lot more interesting than it currently is. Thoughts?
