Microsoft Hailstorm project, announced in 2001 but scrapped before it was launched, sought to make Passport the core of the whole world's web identity. In 2008, major web properties like Google and Facebook are still fighting identity wars. “Microsoft just gave that up,” Microsoft's chief architect of identity Kim Cameron said at Microsoft's Professional Developers' Conference (PDC). “That's the importance of the announcements we gave yesterday. Microsoft said 'no'.”
Those announcements, made at the show, were about the identity product codenamed Geneva, which includes a server, a code library for applications, and the CardSpace client buried in Internet Explorer 7 and 8.
