Mesh networking cellphones in New Orleans.
Why aren't there ad-hoc battery-powered "cell towers in a barrel" that could be "bombed" or floated into disaster zones to turn the thousands of useless cell phones in people's pockets into a crisis mesh network.
(Answer this question, and we can deal with the problem of recharging the cellphones next. But look: today's cellphones are powerful receivers and transmitters and computers. In crisis they should be re-purporseable, whether the telcos like it or not.)
This is not a rhetorical question. Phone Phreaks, this is your moment to shine.
