Windows/Mac: Mikogo sports the basic features you'd expect from a decent desktop sharing tool: whiteboard functionality, mouse pointers for participants, and remote control. Where Mikogo shines is one-click reversal; you can nearly instantly switch from the current desktop to a viewer's desktop.
Mikogo places strong emphasis on remote desktop sharing as a teaching tool. You can draw on the screen, you can give control to other participants so they can try out what you're teaching, and you can easily reverse the situation so that you're viewing and controlling their desktop. It's a perfect tool for those times you're showing somebody how to do something on your desktop and they tell you that it just isn't working when they try it on their own. One click, a confirmation from the other party, and the sharing tunnel is reversed; you're able to work right on their machine.
In addition to easy sharing and desktop reversal, Mikogo includes a scheduling component. You can easily create a schedule for your organisation of tutorial sessions, schedule them, and email the session information to participants. Each Mikogo session includes a conference number so multiple participants can easily talk in a group setting while the demonstration is in session. Mikogo also includes screen recording tools so you can record your tutorial sessions for archiving and future reference.
Mikogo is a free tool, available for Windows and Mac OS X. The session creator needs to have Mikogo account and the full Mikogo software installed on their machine. The session participants simply need the code for the session and a small helper application (which they will be prompted to download when they visit the link to join).
