Arbitrary items can be deposited anywhere using the Nav Sat View (at least in Multiplayer)

As server host, I can click on other players in the UI and open their inventories. While their inventory is open, if they open NavSat view, I will instead see their NavSat inventory. If I place items into their NavSat inventory, items do not seem to stay in that inventory BUT it doesn't prevent me from placing the items either. Instead, the items are just placed on the ground at the location of their NavSat avatar with a deconstruct flag.

This can be exploited to place arbitrary items from anywhere onto the ground anywhere else that is NavSat viewable.
