vanishing cell phones: truly hands free (the walls have ears)

so why do we carry cell phones ? with iris recognition and fixed infrastructrue, the environment should be the phone - any device nearby that can pick up your voice, and has a speaker, should be enlisted as part of the phone net - we then just "speak into the air" and "listen to the voices"

it would look less loony than wearing those STUPID BLUETOOTH HEADSETs, and would be much cooler in terms of battery life:)

the walls have ears - even on a beach, this should work (suitable sub ocean woofers could modulate the remote speakers voice and generate the sound in the surf).

true ubicomp, like nature, will be made of 1 trillion weird hacks like this, just to get around the problems with recharging and pollution from nicads etc...
