I wonder if you could &quot;bypass&quot; the browser by having a socket on your box that connected to a websocket server (?) that then forwarded your request to the remote box. I haven&#x27;t had coffee so I&#x27;m probably missing something.<p>Edit: <a href="https:&#x2F;&#x2F;github.com&#x2F;mcavage&#x2F;node-ssh-agent" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mcavage&#x2F;node-ssh-agent</a> is interesting.<p>You could have a browser extension that connects back to a local daemon.
