I think one of the corporations (like Xang Xi) should have a special membership mission not unlike the military sign up that gives you money/exclusive ship/weapon/etc. for every 50th ship you buy from them. (While supplies last, ship must be at least 1,000 credits, see you local Xang Xi station for details...)

This would make sense for the corporation, because it would attract pilots to home there who normally home at Corvus. This would work for some pilots, who are buying taur 3's anyways, but the corvult fans and people with Corvus faction but no licenses would still home at D-13.

This would also encourage people to be more dedicated to a faction. The membership requires you to maintain a high standing with them, so you will think twice before griefing a player at their station.
