Does this have a WebRTC data channel client implementation, or does it solve more rudimentary aspects of WebRTC such as passing offers and answers (i.e. signalling)? This node module [1] is a client for data channels (but sadly no native Windows support yet which is a needed thing [2]). Once more widely adopted, WebRTC will be a great data communication method between users of all sorts of common-user desktop applications, not just browsers, mainly because of it's NAT traversal techniques and encrypted-by-default requirement. In some instances a TURN proxy may be required (and the popular one [3] isn't the easiest to setup, and doesn't have a native-Windows-not-Cygwin install). This is especially true for users behind large corporate/government networks that don't give you a single public IP per machine.

I have done a lot of work w/ WebRTC data channels recently and I am working on a POC for hosting one's own "page" (i.e. facebook-esque profile page) themselves. WebRTC I think is the best technology so far for the decentralization of internet data from hosted servers to users. It still requires some server side things such as signalling (the handshake), STUN servers (external IP discovery behind a network), and TURN servers (proxies for complicated networks). By packaging up those three things into a single server that can be easily deployed by someone you trust (i.e. some kind of regional "manager" of sorts) and having good software to display web content over WebRTC data channels, a neighborhood-level darknet of sorts will be very feasible for even non-technical users.
