It would be useful in large file server installations to be able to have the contents of multiple folders, even from multiple servers, merged into one view. \CORPFILE1\HOMEDIRS could provide an aggregate view for \FILESERVER1\HOMEDIRS, \FILESERVER2\HOMEDIRS, \FILESERVER3\HOMEDIRS

This introduces an issue during file creation in this structure - where does the new file or folder go? A Windows Explorer extension could prompt for creation target, though there may be more elegant solutions.
