Cool, that's exactly the type of thing I was picturing. Is this used or packaged in any major Linux distribution besides ChromiumOS? I'd like to try out living inside this for a while (probably in a fullscreened VM) but CrOS is a bit too restrictive/unfamiliar as a userland for me to want to attempt it there. I guess Crouton exists, but I'd be afraid that Crouton would add an additional layer of impedance-mismatch to the VT that isn't there when just using it raw (like the kind you get when using tmux-in-ssh-in-tmux.)
