TLS would seem like a poor choice, a messaging layer approach like S/MIME
would be a better fit. And who knows if it hasn't happened already.
The big problem technically would be conserving your supply of one time
material. You have to exchange that out of band if there is going to be
The big problem marketing wise would be 'Power One Time Pad' and its
thousand copies. For most of us, 'one time pad' is a sure fire sign of
crypto snakeoil. Instead of a one time pad it is invariably an untested
