I don't think there is a house that doesn't have a base plonked infront of it, however I think its usually owned by the official factions military (Atleast it is with Liberty) and is atleast IFF'd to a house lawful faction.
Why, exactly, can the base not just be IFF tagged as KNF? I highly doubt anyone would notice, other than certain people noticeing its stopped trying to murder them, and surely it'd still be shooting the enemies that you fear will attack it.
Wouldn't this be a win win situation for everyone? Wheras the current one is definatly a loss for many traders, otherwise this thread wouldn't exist to begin with.
