British SOE used one time pads in WWII, printed on silk so they could be easily hidden and destroyed. Read Leo Marks's "Between Silk and Cyanide" which describes this and may be the best book ever on crypto UX. You may disagree, but I think so.

One time pads, of course have at least the operational issue that you have to have as much pad material as message material and you have to hard-stall if you run out. 

As a mental exercise, assume that you have a low-latency, high-bandwidth mechanism to transmit pads, something suitable for use on the Internet. Now -- why can't you optimize by instead of transmitting your pads with this, just transmit the message?
