Chaffing and Winnowing

Tons of people sent in links to various articles discussing Ronald Rivest's Chaffing and Winnowing technique of 'encryption' that isn't encryption. And it's legally exportable under US laws! Basically the technique multiplexes text from the the actual message with 'other' stuff, and only the intended recipient can sort the mess out. Very interesting. Thanks to Tyson Dowd and Kevin Fu who were the first to send it in.
