I'd love to see a mod, whereas you can sell well-proven bots, hearty freeze-dried meals, or stout booze from your colony. Even things like excess energy or oxygen must be of value in deep space. I don't imagine that it would be too hard to implement, but I'm just a casual player - not a modder.

If someone was really, REALLY savvy, they could create a trade-commission - whereas an outside agency would contract your base to produce (x) amount of (x) in a certain amount of time for a promised amount of (x) in return. Adding a little more trade/commodity exchange to the game would spice things up a bit, I think. Especially if it added even a cursory time limit to a player's activities. This would also encourage players to try rushing radio outposts and actually consider buying the GMO options for something other than unlocking achievements.

Of course, any base with a history of profitable production might see more and earlier "Security Problems" than a financially struggling and xenophobic base of similar size...
