I've had a few ideas for a rather militant "peacekeeper" organization, though it was rather spiritual and based on principles quite far from straightforward. If the vigilante ID let me hit Zoners (being people who give off the impression that strict government is not necessary, and thus a nasty counterexample to any propaganda) I'd probably have tried it for awhile, see how it went, but alas, that ID is quite useless.
Eh, specifically hitting Zoners seems unnecessary with the withdrawal of their stuff from house space. I could see this during 4.84 when everyone and their dog was a Zoner just to claim pirate/diplomatic immunity while they powertraded or farmed NPCs above populated planets in their Battlestars... but now, I don't think there's a point. People finally did start hitting the Zoners, so it's not like they lack enemies, even though the list is lighter than most.
