This could not have dropped at a better time for me! Thanks for putting this together! I was not looking forward to trying to figure out a TURN server, so I'm pretty excited to give this a try.

Awesome! Yeah I have been doing WebRTC for a while and it's still always a pain to get this stuff up and manage it, I would love to hear what you're building and have you give it a try, feel free to hit me up on discord, username @lherman_cs

FINALLY.
Really getting sick at WebRTC services that don't support TURN properly. And people with CGNAT or some type of symmetric NAT often have no choice.
Then half the people tell me it's not necessary, they never had any problems bla bla... well there's tons of people for whom it often doesn't work at all.

Yeah, if WebRTC is the only communication channel, TURN will be needed, especially doing p2p. LMK your experience if you have any questions, hit me up on discord @lherman_cs

jupyter-collaboration is built on Y Documents (y.js, pycrdt, jupyter_ydoc,) https://github.com/jupyterlab/jupyter-collaboration
There is a y.js WebRTC adapter, but jupyter-collaboration doesn't have WebRTC data or audio or video support AFAIU.

Is there an example of how to do CRDT with PulseBeam WebRTC?
With client and serverside data validation?

Is there OIDC support on the roadmap?
E.g. Google supports OIDC: https://developers.google.com/identity/openid-connect/openid...
W3C DIDs, VC Verifiable Credentials, and Blockcerts are designed for decentralization.
STUN, TURN, and ICE are NAT traversal workarounds FWIU; though NAT traversal isn't necessary if the client knowingly or unknowingly has an interface with a public IPV6 address due to IPV6 prefix delegation?
WebRTC’s capabilities are amazing, but the setup headaches (signaling, connection/ICE failures, patchwork docs) can kill momentum. That’s why we built PulseBeam—a batteries-included WebRTC platform designed for developers who just want real-time features to work. What’s different? Built-in Signaling Built-in TURN Time limited JWT auth (serverless for production or use our endpoint for testing) Client and server SDKs included Free and open-source core If you’ve used libraries like PeerJS, PulseBeam should feel like home. We’re inspired by its simplicity. We’re currently in a developer-preview stage. We provide free signaling like PeerJS, and TURN up to 1GB. Of course, feel free to roast us
