Yes as Jovial was saying, your ZOI should not strech to far as some clans have had the problem of getting started because their ZOI was way out of their own space, you should try and confine it to Bretonic space and its surronding systems Tau's Omega 3 places like that. For instence for anit smuggling i would recommend keeping an eye out in Dublin/Leed (by the Magellen JH) for Conterfit software and Deuterium coming from Omega 49 to Kasuri space, as for pitrating bases: LD-14 and Stoke mining base also in the Leeds system is very good for that by the Eco pirates who pirate the taders there and again Omega 3 ( mainly Corsairs in that area).
As for the alien threat, that would take you out of Bretonic ZOI to go to them but if they attack us its fair game.
Hope this helps you in what your trying to do here and hope that all goes well for you.
