I've been quite reliant on MS SharedView. I have found it to be faster than VNC, and also allows for highlighting of the other person's screen without needing to take control of the mouse and can be used behind a NAT firewall very easily.
With the release of IE9, SharedView now crashes and a fix does not seem forthcoming. Are there any fast alternatives that allow for the same features (easy use behind a firewall, speed, and highlighting).
Welcome to Microsoft SharedView Effective January 31, 2012, the SharedView service has been discontinued. For information about Microsoft services that deliver similar features (such as Office 365 and Lync Online) and free trial offers, visit http://www.microsoft.com/office365.
