Você pode experimentar o multiusuário
screen can allow multiple users to access the same session. This can be useful for all sorts of information sharing, from helpdesk applications to extreme programming. By default, multiuser mode is disabled, for security reasons.
Exemplos
Add user phil with password moo, gives him full permission to everything:
acladd phil QSsUHy/lmL5CM
Remove all of phil's permissions (but he can still connect to the session and view all windows):
aclchg phil -rwx "#?"
Allow phil to write to windows 1, 2, and 7. Also allow him to run the commands select, next, and prev. Add a new user, bob, and give him the same permissions:
aclchg phil,bob +rwx 1,2,7,select,next,prev
