It’s about time a mobile phone with out of the box meshing capabilities existed. The cost of it could not be subsidized by a data plan, since communication with it would be free (no need for cell towers). The only ongoing cost would be the electricity needed to charge the battery, and any repair costs. In sufficiently dense areas it would be golden. Talk about network effects- the more people join, the more robust it would be, and the more distance it could cover.
