Hello there!

Here is my idea, i will try to explain it fast (since there is night already - 0:22). So, quickly:

We all use Auction House to place our stuff for sale. And also buying from there (or winning) other people stuff. So, we place in AH stuff and get money for it. My idea of "Request House" is post in it MONEY, for a stuff. EXACT stuff. Here how it's work:

CURRENT:
Stuff => Auction House => Money

We got Nice Calibur UV (CTR:VH) and we want to be rich soon. We posted, it was sold we got money via mail. Everyone like mail, from AH, right? =)

IDEA:
Money => Request House => Stuff

We are looking for Antigua (Slime: Med). Posted money in Request House (for fun - CE Only). And Get our Slime: Med Antigua via mail (someone rolled UV, get it and don't know what to do with it... He go in Request House to check). Antigua must be unbound before Request House can accept it.

So, here is idea. Not complete, but i think interesting.
