I came across a nice java applet capable of plotting data points on a globe, and spent some time using it to plot the list of schools registered in the list of schools using debian-edu. If you get a java-enabled browser, point it to <URL:http://www.skolelinux.no/testskoler/map/geocode.html>, and have a look. :) To add your school to the list, visit <URL:http://www.skolelinux.org/no/user_experience/test_schools/test_schools_add>
