Collaboration guru Ray Ozzie, the founder of Groove Networks and the creator of Lotus Notes, was in the audience at the Identity System presentation and came away impressed.

"Today's business environment is a mesh, not a hierarchy. Asking someone in IT to grant access is clumsy," said Ozzie, whose company, Groove, has a partnership and investment relationship with Microsoft. "This puts sharing into the hands of people who control their personal information and have control over relationships."

Ozzie said Microsoft's challenge is execution. "There is lots of code, lots of moving parts, but the design is solid," he said.
