One missing thing in the puzzle pieces is a "draw from the nearby logistics providers" and "send to nearby logistics providers"; for example, so I can make a crafting drone that isn't super specific about everything it needs to draw from or send to.

Neither are necessary.

• "Draw from providers": set up a chest with a Requester Frame, and use a "Import from Inventory" piece.
• "Send to providers": set up a chest with an Active Provider Frame, and use a "Export to Inventory" piece.
