EduVNC
EduVNC is a browser based remote desktop tool. It is similar to VNC in function, but uses a web browser with HTML and JavaScript (AJAX technology). They provide both MSI and EXE installers. There is a free license for school and non-profits and the rest are pretty cheap. My school uses it allow students to view the instructor's desktops when they can't see the projector that well.
The EduVNC website with the installer is here: http://www.EduVNC.com.
