I believe GNU Screen supports mirror mode (read-only) and pair mode (one shared cursor), but rogue mode (two independent cursors, shared terminal) is the real differentiation from GNU Screen.

Great for remote teams who are heavily command-line based (developers and deployment folks).

Can tmux give two client the same window, but different panes? This means they can see each others cursor on another part of the window.
