Unfortunately the browser still can't make the kind of network connection needed to transport a terminal session to a remote computer natively. afaik all the tunneling solutions are pretty clunky/insecure.
I'm curious to see if this weird stack gets ported to the Googlebooks or if they just make a mouse-friendly Android app instead.
There's even some decent options to bridge further the other way, from a terminal to wss back to a terminal based, server hosted, application.
