Microsoft SharedView: another alternative for WebEx and GoToMeeting

Part of the bundle of software that Microsoft offers for Windows XP, Vista and 7, you will find a nice little tool called SharedView.

Brief Description

Connect with up to 15 people in different locations and get your point across by showing them what's on your screen. Share, review, and update documents with multiple people in real time. A Windows Live ID (Passport, Hotmail, or MSN) is required to start sessions, but not to join sessions. New in version 1.0: we have added a web based join experience to make SharedView even easier.
