Yugma- Desktop Sharing and Collaboration

While at the NCaect conference, I learned about a free web 2.0 tool called Yugma. Yugma allows you to share your desktop in real-time. At anytime, you can empower an attendee and have them take over as presenter. Their desktop is then shown and they take control of the mouse and keyboard. There is also a built-in whiteboard feature for collaboration. Yugma can work with Skype if you want audio or video with the presentation as well.
