Co-Presence Logistic Example

I yet have to publicly document the catastrophic failure of my yet biggest experiment in co-presence transportation as of Christmas 2013. But today I am lucky to document a single successful transport in which I myself took a crucial part. For an introduction in the concept, please see my 2014 paper on our Implementation for Physical Objects Sneaker Transport.
The object in question was a carton box of roughly 40 cm side-length. It was loosely closed and contained two laptop computers, lecture notes and other learning material. And the only reason I know and disclose its contents here is to provide an estimation of the value that has been entrusted to the transportation chain.
The first leg of its route took place within the origins house, from a flat on the second floor to a flat in the basement, where it waited for two days to be picked up by me, July 30th afternoon. Neither I nor the custodian in the basement where actually known to each other. The actual authentication data I provided for the handover of the box was the knowledge of it being there. I then took the box by car (where it was stored for a night and a day) to Bremen over a distance of roughly 300km.
The box then went into storage (my garage), situated a mere hour by car from its final destination until it was picked up on a Monday, August 17th, at about 3~pm. The object then overshot its destination (somewhat south of highway A1) and went to Hamburg for a distance of about 150 km. The carrier was personally known to me, a relative of the destination and authenticated and coordinated by the destination of the box via mobile communication (voice and text).
The final leg of the path was again undertaken by handing the box to a relative in Hamburg. On August 18th this carrier took it the remaining 100km to the destination where it arrived around noon the day after it left my garage. The successful delivery was communicated to me via (unauthenticated) text message.
Compared to a fully automated transportation system the manual management overhead of establishing the first and second storage, as well as coordinating the final legs of the transport, must be considered to be very high. Nonetheless, the experience, being a very rare event, was not to be unduly complex and seemed to be within the bounds of standard social behaviour. Risks at all sides where consived by me as being very low as all parties share a long-term trust relationship to origin and destination with little doubt of mutual interests in continuation of relations.
I actually assume that these kinds of transportation are fairly common among people within a community of any kind. It stands to reason whether this can be improved in a way to properly work among strangers.
