Mikogo

Mikogo is an online tool to share your desktop with up to 10 people over your web browser. The image on the screen will be seen by any participant who joins the meeting.

Mikogo lets you not only show everyone the image on screen, but also control the rest of the computers remotely, send files, and change presenters.

Other interesting features included are the possibility of hiding any running application you don't want shown and encoding through encryption algorithm AES 256.
