Package receipt devices for houses

I remember in the early days in discussions concerning e-commerce and secure package delivery, there was talk about creating/installing package delivery devices for houses, including even the capacity of refrigeration.

Someone sent an article about this to the Takoma e-list, and it included the above image.

Something like this, maybe even these particular versions, was installed in many houses on Warwick Street in the Rosedale Park neigthborhood in Detroit, where I lived from about 5 years old to 8 years old.  I used to crawl through them for neighbors who locked themselves out.

We called them "milk chutes."

Even a door-based device like a doggy door, but code activated could work (exception for the refrigeration part).
