I've been participating in asteroid occultation measurements for a while now. To facilitate the creation of maps of the events I created a new website that uses dynamic data rather than static to display events. In the process I learned a few things about how to automate windows applications using Perl (check
http://sourceforge.net/projects/winguitest/ ), creating dynamic Google Maps using AJAX and using MySQL with ASP.NET. I also learned a lot more about operating
winoccult, a program that calculates and displays occultations of stars by asteroids.
