Webrtc data channels transport

Pions repo is a 100% webrtc server and client.

Now I know web have grpc and it's cross language etc but I am exploring use cases for webrtc P2P with protobuf as the serialisation.
Using protobuf with sandglass is an easy layer to build btw

So I am raising here to hear people's thoughts on I retesting use cases for this first

1. Would webrtc channels make cloud deployment easier since on clouds getting a stable IP is impossible.
   I have read that we etc solves this

2. Would clients interacting with sandglass servers be a good way to handle network hole punch ?

Anyway hope you don't mind me raising this in the issues
