trading while offline/not present? (suggestion)

[Indomitus 388]

I had a thought a bit ago, with the talk about true cooperative modes and somewhat "large" scale trading/buying economies set up on some servers...  Wouldn't it be interesting to have a sort of "bazaar" functionality, where a player could place items kind of like placing them in storage, set trade values for them, and allow any other players to trade with that little storefront at any time, even if the owner is not there.

Visually, it could be a small table, with the offered items displayed on top (but not pickable).  Fancy versions could have a colorful awning.  The number of offered items would probably have to be limited.  Storage for offered items and received items could be separate (or just virtually separate) and accessible by use of keys or combination locks.
