Ever was explaining something technical to someone on the phone? Don't you just hate when that family member asks: and where is the OK button?
Feel free now with this new tool you can share your desktop view and just point him/her to the hidden OK button. This application is (obviously) integrated with MSN passport and MSN Messenger (though it can function without Messenger). You can even specify handouts that attendees can download (So they don't ask you the same question again :D).
The down side of this is that it is still in beta and it doesn't support chat (voice or text) with the attendees yet.
