Worked with Professor Nicholas Rostow today. He is a Visiting Professor and teaches International Law in the Political Science Department.
The issue he faces is the amount of time it takes to find and display a map when lecturing. I suggested he use PowerPoint (needed a tutorial) and using the LiveWeb plug-in he can paste in the URL of a live Google Map and have it embed right into the slide! It also works with web pages - automatically refreshing the page every time you visit the slide.
Here is an excellent quick tutorial from Eugene O'Laughlin of the National College of Ireland, Dublin.
