Microsoft is beta testing a new tool called SharedView that enables colleagues to share documents or demonstrate an application over a network or the Internet. Up to 15 people can join a SharedView session, although only one application can be shared at a time - not a full desktop.

WebEx and other services don't need to be scared just yet, however, as the service does not offer true collaboration - individuals must request control from the person who initiated the session. Users can still participate without control as each has a special pointer that can be used to highlight and discuss areas of the screen. SharedView requires Internet Explorer and a Windows Live ID.
