group/user account income

I think that there should be two or three checkboxes under origonal or copy for sellin in which you could choose user, group, or 50/50. user would make the profit from the sale go to the seller of the object, group would make the money go to the gruop's fund, and 50/50 would split it in half. this could really help smaller groups generate some revenue, and lessen the load on big groups with a group store or such.

I would simply want a

bought(key id, integer amount, integer perms)

(id == key of buyer
amount == purchase amount
perms == bit field with values such as OBJECT_MODIFY and OBJECT_COPY
which state what the buyer can do with the bought object.)

event. so scripts can do what you propose automatically.
