I've been thinking, how about something that hides your identity and your faction, so that you could become a pirate.
We could have a system where every ship has to have a. iD, but players can choose to not have an ID, but if they did that, then they would not be bound by any laws, and could attack (and be attacked) freely.
I'm thinking this could give a good game mechanic for space pirates (half the fun), where someone could use a device that hides their name, and use a pirate ship, without risk of violating their political relations (unless they were captured and found out)
So if your ship had an ID, it would be bound by the laws of whatever ID it has, but if it had no ID, then it would be a pirate ship
