Simon's Braided Stream Cipher

William "Alain" Simons proposal for using a really-random stream to select between multiple data channels on a bit-by-bit basis. One or more of the channels might also be really-random, in which case new key material can be transported to the far end as a side-effect.

Of course, if we are allowed to expand the ciphertext by 2x, virtually any cipher can transport key material in a separate message.

[Here at least one Simon and Ritter exchange was lost.]
