Holographic Sonar Cryptography

Atomic Snarl writes: "New Scientist.com has this story on how to encrypt a underwater sonar message using multiple sound path timing. By detecting and adapting for the current variations on underwater sound channels, the transmitted message can be received intelligibly only at a single point. This holographic approach suggests a method of web encryption using multiple hop paths and ping times to create a message which can only be decoded when received at a specific target node!"

Further, Holocomm's "delocalization" feature can be seen also in SHA-1, where *all* output bits change when one changes a *single* input bit.

Wouldn't that mean that if you changed two input bits, all output bits would stay the same?
