And what if within those 30 min a swindler just sells your crafted materials? In what way could SE prevent this from happening? Even if you said; well the person who posted the request would get his materials back, what happens to the swindlers money he made from selling the items? Does it subtract the costs he made from the materials? What if he traded the money to someone else, or bought something and has 0 gil remaining? Does he/she incur a negative gil balance?

I like the system, I like the idea, but I feel the only way to make it work is if the crafters don't actually get the supplies in hand, they would have to speak to an NPC and the NPC would say would you like to craft this for abc reward? Yes > crafted item is made and is automatically sent to the mog house/whatever method of pickup--without the crafter ever holding the materials or the finished product. So if that is the case then why just give that ability to our wonderful Market Ward buddies?

I don't know, like I said I like the idea, but I think some refinements are in order. :/
