Some kind of networked inventory v0.1 - turns out it's a PITA (let's resolve that another time). Item definitions can define prefabs for when an item is consumed/equipped (not impl yet), can also define a custom Item prefab for even more extensibility., world model etc for future. Basic API for giving an item (host), moving an item from one Inventory to another based on slot id. Mostly everything is component/game object based but Inventories must be Host controlled.
