Microsoft SharedView
Found this relatively useful tool from Microsoft (still in Beta) that allows you to share
your desktop in a virtual meeting with friends colleagues or anyone else for that matter.
The installation is simple (very lightweight-4MB), easy to setup with a Windows Live ID
and you can start creating sessions (check out the feature that adds a name tag to a mouse
pointer-so you know who is who...):
