Your problem might be how they change the files, if via FTP, but...

- Move the public_html dirs
- chgrp www, chmod 640.
- symlink in the home dir

http://httpd.apache.org/docs/2.2/mod/mod_userdir.html#userdir

Example:
mkdir /var/userweb
for USERDIR in /home/*; do
        if test -d ${USERDIR}/public_html; then
                destdir=/var/userweb/${USERDIR##/home/}
                mkdir ${destdir}
                mv ${USERDIR}/public_html ${destdir}/
                ln -s ${destdir}/public_html ${USERDIR}/public_html
                chgrp -R www ${destdir}/public_html
                chmod -R u+w,g-w,o= ${destdir}/public_html
        fi
done

In httpd.conf:
UserDir /var/userweb/*/public_html

That said, I don't really understand your 'ls' paranoia. If you don't care 
about ls, you can set user's umask to 0027 and rechmod all files to 640. Have 
users in their own group and have */public_html group www. /home/username 
then has to have 755 in order for apache to get to public_html.

Problem with today's modular software: they start with the modules
    and never get to the software part.
