I think that making a high-value commodity that cannot be bought by any other but OSC ID would be pretty good idea to boost interest into that faction, since it does offer nothing. And it would be pretty weird if OSC had to trade ores to earn.
What about remaking VIP commodity, boosting the price 2x and restrict it to the OSC ID, only? As far as I remember, it can be done via code used for restriction on the Wild equipment.
