Beartooth
http://www.beartooth.com/Decentralized communication platform
Beartooth allows iOS and Android devices to communicate when the cellular network is unavailable, failed, or congested. Skiing fresh powder, immersed in Stanford football, or dancing at Coachella, you can reliably connect with your group in ways that were previously unavailable. Beartooth allows for true peer-to-peer communication, between the devices, completely bypassing the Wi-Fi and cellular network.
