Yes, you are right, Mordechai. My point was:

a) Prove that you can implement chaffing & winnowing without
   bandwidth overhead. I agree that the final schema doesn't
   resemble C&W anymore :).

b) Prove that you can use signature schemes, strong and exportable,
   to achieve confidentiality. In that way, my objetive is the same
   that Rivest had.

I'm happy knowing I can use full strengh signatures to keep my secrets,
secret :)

In the Rivest's paper you transmit, indeed, all the 2^n plaintexts for a
n bit length };-).
