Hey here's an idea. Everyone is fed up about this war, so in a bid to end it SolaR or Phoenix or whoever the dominant Zoner group is make a draft for a O74 treaty with the Corsairs and Order (both groups get their fingerprint on the treaty, like guaranteed free passage and similar minor rights), lolgate swarm ensues and Corsairs and Order secure the system for SolaR/Phoenix/whomever who will then get ownership of O74.
It is ridiculous that there's a system this close to Gamma without having any form of ownership/leadership - no one to address when things go sour and Zoners war and destabilize the entire region. It's unacceptable both in and out of roleplay. And doing the above would add some nice lore to Zoners, that some vie for power and pay the price - no more Mary Sue let's all be friends etc. etc. Other Zoner groups like TAZ would of course have to agree on the ownership, but at this point I think everybody is more or less fed up and will agree to most terms to have peace and quiet.
Once ZA is flushed, Order, Corsairs and Zoner owners of O74 could build a jumphole guarding base and share the password and make some sort of "peace, harmony and unity" event out of it, and use it for future diplomatic talks between the 3 groups, sort of like that Cylon/Human base in the beginning of BSG. We'd have an actual roleplayed base too.
It would round things up nicely, O74 would get under control, and Order, Corsairs as well as the new owner will all gain from it. Some RP could spin out of it; and we would have the first and only Zoner group that paid the price for having power. Win, win, win. For once it wouldn't boil down to stupid arguments regarding who has the "moral rights", who is the most "Zoner" and who is the most "RP" like these forums as well as in-game talks are flooded with these days, clotting up the conflict and making it more of an oorp than inrp venture - it would be concrete and realistic, add some much needed ambiguity to Zoners, who could go "Get out ZA buddies, SolaR/Phoenix/etc. owns this place now!" and have that backed up by groups that are allowed to fry Zoners per their ID.
