I need WebRTC signaling and after looking around and trying many things, I’ve successfully used experimental pubsub in js-ipfs to perform it. See the tech demo at https://github.com/cretz/webrtc-ipfs-signaling. For those unaware, WebRTC requires out-of-band negotiation and there aren’t many (any?) easy approaches w/out maintaining your own signaling server or relying on a (usually commercial company). Please take a look, feedback appreciated/welcome.
(also, if anyone wants to help me figure out why, on the second part of my tech demo, js-ipfs can’t see published messages from embedded programmatic go-ipfs, I would appreciate it)
