I agree with Mista, that if the items are ever sold, we will eb able to distribute teh value more evenly between everyone. The distribution is not meant to be equal money share, but to give an optimal use of each item, and thus, raising the survival of the group.
I think this group is thight enough and they are not seeking fortune, even if they will not drop a chance to get some ressources, as it is always usefull when you have some quests to accomplish.
Also, I think with time, things will equilibrate. Look at Khlia's case. In the first distribution, she got nothing (she carries the gems). In the second distribution, she ended with a tome that is better then a pearl of power (5th level), which worth at least 25 000gp. That bring her back nearer the average and even beat Rogan, who has a loot around 20 000gp. And I don't even have teh sligthest idea how much worth the items of Jango, but it gives him a great flexibility with his spells.
Once we will get out of there and finish in a city, we will see which items we want to sell, who got what and try to distribute the value more evenly as possible.
