I still don't see any valid reasons to reinvent input_item and 
input_item_node.

And in any case, there are reasons why input_item is not tied to an object: 
the item can outlive its maker (while one object per item would be too heavy).  
So you cannot have media source tied to an object either. It's either going to 
break immediately, or become an enormous mess and break sooner rather than 
later.
