Yes.  It's quite clear how shadowfs should work.  There are (or
'should be') some differences to unionfs however.  For example the
limitation of having only one 'upper' fs layer and one 'lower' layer
is not a good thing.  Furthermore the Hurdish shadowfs should take
advantage of the fs-notify feature of existing fs servers, which makes
it possible to keep the in-core constructed shadow-fs in sync with the
underlying filesystems...
