If you like this, you might find my little Tmux plugin[0] useful - it's meant to make continuing your terminal work on-the-go as simple as possible:

  - you're in tmux
  - you do some keyboard shortcut
  - you're presented with a QR code
  - you scan the code with your phone
  - your active tmux pane is now in your phone, you can see output and send commands

Behind the scenes, it is also using WebRTC.
