This is a neat idea, but still requires running a local executable. To ease adoption, a web app would be better.<p>So how about a ngrok like service where you just open a page to forward local traffic ? The vulnerability we've seen yesterday, "A web page can see your local servers", suggests it's doable. The webrtc code needs to open a HTTP connection to the local server. JS code would proxy all requests coming through an external hostname to this local server. Is this doable ?<p>"I can see your local servers" <a href="https://news.ycombinator.com/item?id=20028108" rel="nofollow">https://news.ycombinator.com/item?id=20028108</a>
