i think you've misunderstood what i was saying. the OTP is definitely not a practical method of encryption, obviously.
and no, OTPs do not require that the that any secure relationship be formed forward in time.
in fact, restricting "crypto" to "crypto that people can use in practise" doesn't rule out the OTP - it was used with great success in both world wars, owing to the fact that agents were able to share keys before the fact, use them once, and then discard them.
finally, at no point would i ever suggest using the OTP as a means of encryption in place of a public key system, especially one with a key of 0s. why you suggest such a thing is beyond me.
