I think it would be really cool to have a bounty system where each nation offers a different reward for a player. They would offer the normal amount for killing one of their bots or players and half the normal amount for killing NPCs or other nations ships. You could only collect bounties from your own nation (if there was a true nuetral option then they could collect the best bounty). Nations would put negative or no bounties on their own members (if team damadge is ever implemented a nation could put a positive bounty on their members that killed people with a negative bounty).
