[liberationtech] Unique Opportunity: Input to CEOs of Smartphone Manufacturers

Hello:

I'd like to see a mesh mode in the mobile phones. There are currently
lots of mesh software initiatives, but I haven't seen any smartphone
manufacturers support this. In the past, they were dependant of
telecommunication companies to sell their phones, but now some
companies are now starting to sell phones by themselves (Google for
example). A mesh network mode would allow users to communicate even if
there's no other conection, it can be useful to conect with peers in a
demonstration or to transmit stream video to them in case police
breaks your phone.
