You can now build a vending stand. The stand can hold items. You can set a price on these items in coins. Any player who interacts with the stand can now buy the item, provided he can pay the coin price.
Ownership: The player who first puts an item into the stand is the owner of the stand, regardless of claims, until the stand is emptied. Please note, however, that, if the stand is on a claimed area (village or personal claim), anyone with appropriate privileges (A village member, or the claim owner) can take stuff from the stand without paying. If the stand is not on a claim, anyone can take stuff from the stand (without black skills). You'll want to build the object on claimed land. The only difference, between the stand and normal objects, in terms of ownership, is that you can interact with the stand even though you normally lack privileges in the claimed area in question (As is also the case with, for example, runestones).
The UI is a bit lackluster, but it should be usable.
You can set a sign on the vending stand to give a hint as to what it may contain. There are six signs atm, but I'll happily be taking requests if you feel you need more kinds. You can also set it to not displaying any sign at all.
The amount of stuff (Measured in number of inventory slots/Volume) that can be contained in the vending stand is determined by its quality level, quite simply.
If the vending stand is destroyed, so is anything contained in it.
It is possible to steal from the vending stand, provided you have criminal actions turned on. Payment rendered to the stand cannot be stolen at present, but that will be fixed.
One thing we really regret about this implementation is that it forces players to use the coin item type in an unnatural way. We can, however, not think of a better way to handle "offline trading" (Not one without much ado, at least) at the moment, and we feel that offline trading is important enough for it to be worth the sacrifice in economic realism.
Enjoy.
EDIT: The Vending Stands, as of now, have their own rules of ownership. If someone has put items for sale in a stand, anyone else taking them will always count as theft, regardlessly of whether the stand is built on claimed land.
