Im all for option 7 and 4 and 6 because it prevents people from being a one man army, there will be a lot more at stake for transporting the mass goods, and the barge wont be used as a mobile base.
This forces *gasps* people to not go solo on their barge missions and perhaps Houses will get their own Jump fleet to use their barges like the Zoners have very well. Would be awesome to see Samura, Repex, and the other two house major shipping companies doing this. It promotes core faction interaction and player base in those factions. There is no damn need to make a "new" faction to make this happen. The barge's biggest blight is their cargo space : Trouble using the damn thing, ratio. Making the cargo hold larger, like 60k. If they are indeed making the Jumping barges 40k off target, this change forces you to have a convoy to ferry stuff back and forth.
Sometimes, when all you want is to gain your freedom, you must be willing to risk it all.
