Genius idea

Encrypted sound. Add a module to your cell phone that encrypts the audio as it leaves the earpiece. Pair this with a hearing aid that decrypts the audio so that anyone able to listen in would only hear gibberish. This would also work across the wire but would require some asymmetric stuff.

Phones really need to be open source.
