thats a cool idea, but I don't' think anything is available to do it. (read: opportunity for you to contribute to the community)
if you are trying to see when someone access your web site you can look in your log directory (/var/log probably) for your web server logs. Apache, by default I believe, creates and access_log which is updated everytime a file is accessed on your web server. you can then use tail -f to keep a running tab.
tail -f /var/log/apache/access_log
