I think this is kind of a portable PO box, or PO box you can franchise. It seems there are things moving to kiosk despensers like redbox, blockbuster, even those change counting machines in the supermarket!
This is like a redbox for delivery. They could easily grow integration with package delivery companies, or they could compete by buying their own trucks and hiring drivers. This service will be very interesting to watch.
Also, can I drop a package in one bufferbox and have it delivered to another?
You want to borrow my snowboarding helmet, goggles and gloves. I drop them in my box, select a destination, and buffer box teleports them to your box. Reverse the process when your done with it. Also, I let it be COD - meaning that you, the borrower, pay for the round trip buffer transfer cost.
