Microsoft SharePoint does everything of WinFS, it acts as WinFS like file-server for office documents. It comes with default schema (columns) and the administrator can add specific company relevant metadata fields. You can group, filter search, create custom views based on metadata. It all works great, but in the end of the day it's just a website and managing more than one file at a time is cumbersome (it's a website not Explorer/shell) and even if one can open directories in Explorer using inbuilt WebDAV protocol the WebDAV integration is ok but it is as featureless as the zip-file support in Windows shell (no rightclick menu entries, no new file, etc.). With a native OS integration other applications could take advantage of the new possible features.
