I've just come off the briefing and question session on the Allied discord and there is a bit more info that may help people, regardless of if (like me) they don't like the no guns stuff, or you are dancing to their tune.
Firstly I will say the chap running the show, Jubei Himure, is considerably more agreeable in voice than in text. Eg he talked at length about there rules of engagement and why they are imposing them. I still don't agree with them, but I do understand them from there point of view. He also said he is well aware that this is causing a lot of upset with people, and he does not like, but it is the safest why for them to achieve there objective, which ostensibly is the same as most of us rifters. However there does seem to be an amendment that help people like me, who want to help Salome etc, but do not want to be following other peoples orders or rules:
Ships with weapons that are not on their white list, will be fine, if they move outside of 1000Ls of a system's primary star, where action is taking place. If you stay within 1000Ls, you will be interdicted/attacked. If you are on that discord, you may then be called into help in fighting. Also, ideally you will be challenged and asked to move 1000Ls+ away first.
Of course given there are over 3000 people now on that discord I expect these 'rules' to be pretty sloppily enforced so I would advise others people, with guns, on Salomes side, to still expect to be considered an enemy by that force. However this does open up a little more opportunity as opposed to a blanket KOS.
Bottom line is that I'll return fire on ships that attack me. And if attacked by my CoR "allies" I'll declare for the opposition. This whole thing stinks of a plot. The leadership has been infiltrated, its obvious. We have been betrayed.
