  I had just envisaged adding a hook to load-file, to allow
 files that are opened manually to be, transparently - or
 conditionally, resolved.

  I suppose you might want to deal with all other file operations,
 but this could, also, be accomplished via hooks, or advice -

  Perhaps it is a lot of work, but it would be fairly simple
 to implement each case, and would only be necessary on w32
 systems, so even a really tortuous `w32-lnk.el' wouldnt have
 any problems on Unixlike systems.

  I'm not sure what you mean by this - unless you are suggesting
 handling the, special, Cygwin shortcuts?

  Under Windows only three forms of shortcuts are used:

        1. The .lnk file.
        2. Cygwin shortcuts
        3. NTFS Hard links

  Hard links are either supported by the filesystem, or aren't
 available - either way no problem.
  The Cygwin shortcuts are simply a text file, more or less,
 containing the name of the real target - dealing with them is
 very simple, if you can insert the hooks in the correct places
 for the loading of files, etc.

  Perhaps I'm missing someting?
