In my setup, syslogd does both -- append the message to the appropriate 
log-file (in this case -- /var/log/auth.log) and feed it to the script's 
stdin. From syslogd.conf:

    auth.info;authpriv.info                         /var/log/auth.log
    auth.info;authpriv.info                        
    |/opt/sbin/auth-log-watch

"tail -F" seems just wrong :-)
