Xenos are about as much a pirate group as any other....they spend time attacking detroit munitions because they need the guns. Gaians I'm sure have funding from less radical eco-freindly groups and fronting organisations, the BD are funded by the GMG, and have their own asteriod, which could easily be a self supporting environment, GC have massive support among the younger populous of Kusari, and also have Cardamine sales to fund them.
The Xeno groups are doing fine, and rping well, so there seems no reason to not give a bit more freedom to the groups who are much like the Xenos. The purpose here is to open up the rules a bit to allow these groups to be RPed as they are presented, and not as the standard pirate, which the mod seems to suggest is all that criminals can be.
Other than that, Sovereign's suggestions seem workable, and exactly what I was going for when I started this.
