Maybe your distribution has already done it anyway.
Yes, but they can change it back to 777 easily. chown root, chmod 070 should do it, as Stefan has suggested. Then, you have the world-writeable directories /tmp, /dev/shm and probably others ( `find / -perm -o+w` to find all ). For /tmp, chmod 000 and set TMPDIR=/home/$user/tmp ( http://en.wikipedia.org/wiki/TMPDIR ) in the session init ( /etc/X11/Xsession.d/ ?) Making /dev/shm unreadable will kill pulseaudio, but well. What about the wall command? Probably chmod g-w /dev/pts/* will do it (in a loop !), haven't tested. Lots of corner cases... Probably fat clients as suggested by Alkis would be easier in the end.
