Hardlinks on NTFS work great when you are using them only from within the
cygwin environment. What happens when I modify one of the hardlinked files
from outside cygwin. For example, if I execute 'ln MyDocument.doc
MyLinkedDocument.doc' and then were to edit one of the files in Word or
some other non-cygwin app.

It depends. If the editor opens the file and changes it, the hardlink
remains valid and both directory entries point to the same file. If
the editor removes the file and creates it new, they are then two
different files. But this is not different from any POSIX system.

There is a native command on WinXP (2000, NT?) to create hardlinks:
fsutil hardlink create /?
Syntax : fsutil hardlink create <neuer Dateinname> <vorhandener Dateiname>
z.B. : fsutil hardlink create c:\foo.txt c:\bar.txt
After once a hardlink is created with Win's fsutil or with Cygwin's ln I
found no means to decide which one originally did create it. So I guess
that Cygwin-hardlinks should work fine for native Win-applications too.
