      Remote terminal application that allows roaming, supports intermittent
      connectivity, and provides intelligent local echo and line editing of
      user keystrokes.

      Mosh is a replacement for SSH. It's more robust and responsive,
      especially over Wi-Fi, cellular, and long-distance links.
