Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Sending a key over the net would be very stupid, however. The entire point is that you do not let anyone see the key twice. Which means delivery has to be physical.

Fine, but if I deal with people all over the world, do I have to visit all of them? am I going to end up with a memory stick from every one? I'm sure it would fail on Practicality

oh, that is easy, also. Oldest known security trick will work for this.
Take USB stick. Mold a clay figure or tablet around it. Sunbake it. -it does not have to be a pretty figurine - in fact, it kind of helps if it is not, harder to copy.  Mail it. Email a photo. Have the recipient compare before smashing. But yhea, you will need a pad for everyone you want secure communications with.

Point of this isnt that a clay figurine could not be duplicated. The point is that it would take long enough to do so with sufficient accuracy that the recipient should notice the delay.

I know you live in Denmark, so I am forced to assume that it has been a while since you last sent anything in the mail...

Take USB stick. Mold a clay figure or tablet around it. Sunbake it.

This assumes that no packages are X-rayed. But a hollow metal object with an opening that looks like a mold mark might work. Insert data stick, fill remainder of cavity with a metal filled clay, solder the opening shut, grind and polish that surface and glue felt over it as a base. Just don't use a falcon.

A cast or formed metal brass or pewter decorative paper weight would do fine -- unless the authorities became suspicious of the sender or recipient, as acoustic or even more sophisticated inspection might be used. A Dremel tool would suffice to open the base in the appropriate place. If one desired to reuse the object just have a back piece that is soldered around the entire bottom edge. But this is getting to be non trivial.

perhaps deep down it's a government scheme to get people using the post again to drive the price up for privatisation
