It would be nice if I can send items to a designated storage like postbox. If there are items inside a chest (or postbox), the items will be transmitted to a designated location at a certain point of time (like in the morning or midnight).
The mailbox can be created using a chest. As a sender, an item frame is attached to the chest, which the item frame can be used to set the destination for the items. For example, if I want to send items to the destination with the address "Foo", I can put any item named "Foo" on the item frame. To prevent inefficiency, the item on the frame can be removed or put inside the chest after the item has been sent. As a receiver, a sign is attached to the chest with the indicator on the first line and the address on the next line. So, continued with previous example, I can address this chest "Foo" to receive items.
I don't know if this is possible with commands, but this would be a game changer on an SMP server, when it comes to selling or sharing items with others. For SSP, this can be used to send items to home from a distant location.
