Have a setup similiar to a mail order delivery service. Log in a request for an item, you can specify ql and item and it comes in a few hours/days (or even instantly).
Couple restrictions on it though. First, an item must be available in stores. I.e. no rare or boss only items. Yes I'd prefer to be able to, but no way FC would even consider it. Second, the item would be very overpriced, multiple times the store price. This makes it so the stores are still useful, but if your willing to pay you can do it a bit easier. It'd also have a positive side effect of sucking some of the money out of the overinflated economy. This is actually a good thing, there aren't enough ways for money to get out of the system as it is. Third, possibly make the terminals to do this profession specific to add 'uniqueness' to the ability, but have the order form specify a shipping address, i.e. the peep that wants the item gets it directly. Thinking crat's would be very appropriate. Also, if its done this way there could be a 'cut' that the crat get, maybe even standardized as a percent of the cost of related to the ql. Fourth, think of a new name for it so FC don't get sued by Fed-Ex .
My only request for thinking of this great idea is that it be usuable by agents using fp:crat. I'm an agent and I only think its fair that I get to use what I invented .
