Thank You. I briefly checked out the websites. Problem at my school is bandwidith. We have not installed fiber optics yet. EPALS allows students to have their own monitored email account. I am thinking about doing some virtual teaching in the near future and this would be nice. Any streaming overloads our network.
With your work in Education Technology like iPod alternatives, I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based platforms, have a bunch of features and free basic service. Here’s a public class recording you might find of interest.
