More links and info on MCMS (Microsoft Content Management Server), though you're unlikely to be as interested as I am:

• MCMS used to be NCompass, before an acquisition earlier this year.
  
• Although it involves authoring pages for the Web, it doesn't support WebDAV, the standard for Web authoring.
  
• Although it supports content syndication, it doesn't support RSS or any other open syndication standard.
  
• Its architecture is based on OLE controls embedded in Web pages, so sites built with MCMS probably can't be used by non-Microsoft Web clients.
