Isn't this essentially a URL shortener for post? The post operator generates an ID for your address, sender uses it to post stuff, the post office maps it back to the address. One additional challenge I see is that if the fees vary by distance, the sender would still get some sort of an idea as to how far away you are, but that is probably acceptable.
