+* call onNodeDBChanged after we haven't heard a packet from the mesh in a while - because that's how we decide we have less than 2 nodes in the mesh and should stop listening to the local GPS
 * add large packet reassembly?
 * optionally turn off crypto in signal - preferably though see if there is a nice way to be a peer of signal/sms and now mesh.
 * change signal package ID - if distributing modified binary
