After participating in the elluminate tour with Sheryl Nussbaum-Beach , I came away excited about the possibilities for education. The ability to have a guest lecturer from across the world is pretty sweet. The fact that in a classroom, you only need one computer in order to be "in" on the conversation is great because there is a lot of reservation re: tech focused around the cost of tech...but with elluminate, you can reap many of the rewards with only a single computer.
The difficulty would be getting the guest lecturer on board with elluminate...getting them familiar with the program, or getting them to purchase the program, although i believe Jeff or Sheryl mentioned that it was free for small groups...?????
