Is there a service (obviously paid) in which you can ship containers to specific address and the will be indexed and stored in a facility.
Then ideally when you need the containers you give them your address and they will attempt to expedite them to you as fast as possible?
Ideally such a service could be based around some of the large airports in the US (similar to Amazon's distributions centers) so you could get 1-2 day delivery speeds.
Now some may argue that his doesn't relate to travel, but imagine how convenient it would be to log onto either a website or dial a phone and get your goods (or replacement goods) with in a couple days. Perfect if you lose your goods while traveling.
