Pod-casting , what a great idea . I can record my own video or sound track. It seems fun but at the same time you have to find the time to record it. It would be a good idea that students have access to create their own pod-cast about a project or a lesson.  I believe that  would be a manner to keep them engage in a lesson, especially because most students love computers and the idea of creating a piece of material with their own voice recorded and the music that they love ,It is priceless.
