I was thinking about something similar to this for personal RP. I am working on some RP for buying a cruiser, and I've worked up a small datasheet on what materials it would take to build one (IE SuperAlloy, Optronics, etc).
My ultimate goal is to purchase and haul all the commodities to the shipyard who OK's my purchase request (in RP petition to governments). You would have to pick up all the commodities throughout Sirius and deliver them to the shipyard, accepting whatever the shipyard "pays" for them. The actual cost of the Cruiser would then be, in RP, the Labor Cost for building the ship.
Haven't fully completed it yet, but hopefully soon. Anyway, it's basically the same idea, only yours is scaled up to include many people. I'd like to see certain factions propose a "reward" for hauling certain items, but only pay them out to appropriately tagged traders as well (read: no "Police" traders). Even the Hispania Clans can get involved here, hiring out-of-zone traders to pick up needed materials.
