[Battlemesh] Nice meshwork project based on cellphones

Hi Paul,

Thanks for your great project!

>> Any progress on the mesh over GSM side?

Following up the question of Benjamin, I am wondering how could you
access the base-band processor of "smart phones" (not features phones
that usually carry one chip for AP+BP) to be able to manipulate the
base-band (changing the frequency to outter bands than official ARFCN
and implementing a layer1/2/3 stack for peer-to-peer radio connexions)
?

Cheers,

Xavier.
