I share my screen a lot with colleagues. During sharing, it's advisable to turn off Aero as it generates much more graphics to send over the wire and causes delays in screen sharing. Some screen sharing apps actually do this for you, some don't.
I'm looking for a quick and convenient way to switch on\off Aero on Windows 7. Ultimately, if I could tie it to a hotkey, that would be best, but any widget \ tray-icon, desktop shortcut would do.
