An update from Robert about FPSE:
"Because Microsoft realizes that the FrontPage Server Extensions are essential to many web hosting companies, the Internet Information Services product team is researching the development of an updated version of FPSE 2002 that will work with Microsoft Windows codenamed "Longhorn" and Microsoft Windows Vista."
