There is an RSS feed of the syllabus for the programming language course I'm teaching. You can subscribe to it in your news aggregator and get a daily reminder of that day's lecture and what homework is due. There are also weekly and monthly feeds if you need a longer time horizon. This is all being driven from iCal on my desktop. This is of interest to students in the class, of course. I was mostly interested to see if I could use this to drive event notifications in an RSS feed from the tool that I use to manage events, iCal. The answer is "yes."
