<p>How about <a href="http://servalproject.org">servalproject.org</a> ? It has tested a wi-fi mesh network at a remote aboriginal community using android phones. </p>
<p>One good thing about dictators' switching off mobile phone networks is at least it stops android phones' potential to sell out activists! A distinction from Iphone's seeming to actually compromise pro-democracy people in Iran! </p>
<p>If a user controlled mesh network can stay up at least in crowded protest areas, progressive activists have a good chance of bringing repression to an end in their neck of the woods. :)</p>
