If you were at the PDC last fall you might have heard about Monad. That's the code-name for a new command shell. Jason Nadal, on his blog, said he was "blown away" by what he saw. Luckily Channel9 Forums tracked down the Architect on the team (officially named the "Administration eXperience Platform" team, the product hasn't been named yet), Jeffrey Snover.

In order to get Monad go to Microsoft's Beta Website and use the code: mshPDC
