Well, Hogosha are already outlawed in Bretonia, and yet you can't do much on your initiative there. You have a fine selection of enemies in the Sigmas, with the only choices left being if you decide to alienate Rheinland corps or not, and Core or RM.
On the Taus side, even more enemies and fewer allies. You get to decide if you (or a group you come up with) decides to be more buddy buddy with the Council, or with the Royals side. Exiles kind of thank you for any support, CR and Outcasts will keep hate your guts most of the time.
The regulations that prohibit House lawfuls from reacting upon occasional offences that happen only outside of their borders should allow corporations to be more daring in their feuds, but also semi-lawfuls to be more daring in showing less courtesy to the Big Money outside of the House courtyard.
I'm a sort of person that loves to avoid conflict, so this faction which I'm a big influence steers in such a way. We lack the aggressive gene some would attribute to the "space Yakuza".
