When I tried to use Microsoft Codename "Tahiti" recently, i got the message that its out of date and must upgrade.
So when I went for the upgrade, I was provided with a new installation with a new name for Tahiti as SharedView.
So the Microsoft Codename Tahiti pre-beta , has been changed to Microsoft SharedView Beta.
So when i installed it, the interface was almost same as before but was fast to login with improved fit and finish.
But strangely it was having a NOTE: Microsoft SharedView Beta may only be used within the United States of America.
As posted earlier , it'll indeed be a very handy collaborative tool for reviewing and discussing documents, codes , sharing desktops.
