Is it possible to make a browser client for this?

I'm thinking it would be really cool if a browser (with assistance from some known servers for the discovery phase) could make peer connections to servers running behind a nat.

It would obviously need to be websocket or HTTP protocol over hole punched TCP so that the browser could make the actual connection without the help of a proxy.

Is this feasible and what's the minimal server setup needed to make it happen?

What if I wanted to write a browser extension instead of deploying servers? Would that work as well?

Start by reviewing the repository's existing server and client behavior, then compare it with the browser, WebSocket or HTTP, and NAT traversal constraints described in the issue. A complete result would establish whether browser peer connections are feasible, identify the minimal server setup, and address whether a browser extension changes those requirements.
