It's quite simple. Alice and Bob ssh into some address@hidden they
can temporarily share. Alice runs "screen" and Bob connects to the
same screen with "screen -x". After this, Alice and Bob are both
seeing the same session, so for example Alice can type "ssh
address@hidden" and Bob can see what she's doing. If Bob needs
something that needs root privs, he types "sudo cp foo /usr/local" and
Alice types her password at the sudo prompt, which Bob doesn't see. If
Bob starts doing something that Alice doesn't like, Alice can see it
in real time and disconnect Bob from her homebox at any time.

Multiplayer ssh is quite fun. :-)
