Ha, that's interesting. I wrote a very similar "sniping" app (for myself not for others) back in 1999. Back then I had a Motorola pager (one of the large-screen fancy ones) and I could receive short messages via email. I wrote a (horribly constructed) Visual Basic app to check the course enrollments and report to me, in near real-time, when a class opened up.
