Is there some greasemonkey script for finding out when somebody dropped a college class that you want?

My university’s online class registration system shows you how many people are enrolled in a particular class. If it is full, you cannot register for it. I know that Facebook has a script that lets you know when someone removes you from your friends. Well, could you also use the same thing to find out whenever someone drops the class you want, so there’s an empty spot? So I can know right away without checking, and hopefully before somebody else registers for it. Or better yet, is there a way to make it automatically register in it for me?
That depends on the security policy that greasemonkey follows, but as far as javascript goes, if it was run on every page load (i.e. setting the filter to everything), it would be possible – however, I’d hope you have a decent internet connection, because it would slow down every page load.
The best way to do something like that would be to run a server-side script on your web server that was run at a certain frequency. it could also be scripted to auto-register you, provided that your university didn’t have some form of “anti-bot” methods like captchas or unique “hidden” ids that would be submitted with a log-in.
