WebRTC P2P apps without centralized servers
1. Use local app server and mdns/bonjour/zeroconf to announce it for signalling
2. use webrtc for p2p udp communications

https://github.com/floatinghotpot/cordova-httpd
https://github.com/becvert/cordova-plugin-zeroconf
https://github.com/cjb/serverless-webrtc
Uses:
* use pouchdb to sync dbs p2p for coordination
