Screen's proper multiuser mode can only be used if screen is installed
setuid root. Weak, IMO. It does add a lot of functionality (like you
mentioned, ACLs), but doesn't seem worth it. So far, screen -x is enough
for me to do newbie walkthroughs and the like. You just have to share
your account with them temporarily, and don't get the advantage of
read-only access and stuff, but it's more convenient (easier setup, and
no setuid install).
good times,
