The Monad blog says:
1. Monad (MSH) has a new name: Windows PowerShell 2. Windows PowerShell will RTW (Web download) in Q4 2006 3. RC1 of Windows PowerShell is available today 4. Exchange 2007 and MOM will be built upon Windows PowerShell 5. The next wave of products will be leverage the same architecture - Admin GUI layered on Windows PowerShell
Side Note: The names of many of the APIs have changed to reflect the new name (basically you'll have to search and replace MSH with PS). We're sorry about the inconvenience of this, we always expected the official name to be the Microsoft Shell or Management Shell so we felt confident that MSH was safe to use. When Marketing saw what the technology actually did and the incredibly positive reaction that customers and partners, they decided that we warranted a "Marquee" name (I'm not making this up). Marquee names are given to those features that are going to be emphasized during the Marketing push. So here is the net of all that: the downside is that you've got to change your API calls, the upside is that you are leveraging a technology that Microsoft Marketing plans to feature widely.
There's also a new blog at http://blogs.msdn.com/powershell/default.aspx
Comment: There's a good overview of Monad at Ars Technica, which only slightly misses the point. MSH^h^h^h PowerShell isn't designed to compete with Python or Ruby or whatever: it's primarily an admin tool.
