Perhaps making only anarchy and feudal systems open to PvP, or perhaps introduce thargoid vs navy battle zones, where you can either turn up in your regular ship or when docked at a certain station choose to enter "thargoid" play where you get to play a pvp only Thargoid pilot that is restricted to the battle grounds...
That said I think just making a "no l33t speak" and "no smack talk" policy would be enough. Simulating realism would suggest against "unattackable" player ships. Perhaps using planetary government ratings backed up by serious consequences for piracy in civilised systems. If you head to Riedquat you know what to expect

Ive rarely ran into unpleasant encounters on the RP server in lotro and in the couple of years Ive been playing I think Ive only encountered "begging" twice (which is another scourge of mmorpg's that Ive encountered.)
Oolites inherent modifiability I suspect would be easier to over come than the single player \ multi player issues, making the holding of player data server side and taking out the oxp scanning and hard coding the ships items etc into the game would be childs play compared to getting things multiplayer
