What's the mobile phone equivalent for physical package delivery? What I mean is that we have a phone in our pocket that goes everywhere with us. When we get a phone call, it doesn't matter if we are at home, at work, in between or somewhere else entirely, our calls and messages find us and come straight to us. How could you do that with physical packages, turning the postal service into mobile delivery?
Well, perhaps the phone is the perfect place to start. If you're expecting a package, you could opt to transmit your current location, via mobile app, to the post office or courier service. Then, no matter where you go, they would be able to find you and get your package to you. This also eliminates the need for keeping postal addresses up to date with companies. When they want to send you something, it can just come straight to you, even if you move house permanently. You don't need to arrange for anyone to pick up your mail while you're on holiday, either, although getting bills at that time might ruin the relaxation.
It might be tricky and creepy in crowds, and in some places you might need them to wait outside for you - if you're at the movies, for instance, you don't need your mail carrier to buy a ticket and follow you inside.
It also raises some privacy concerns, since a system like that would (not just could, would) either be hacked or abused by post office employees. It would make the hard part of a process server's job much easier, but would probably make subpoena avoidance a simple matter of turning off your phone.
Lastly, for very bulky items, you're probably going to want them to go to your home anyway. You don't want to get something huge delivered to work and then have to carry it home on public transport, if that is your custom.

PS - You could probably make it work as a high-end option for couriers.
PPS - As long as it's reliable.
