I can see the benefit of having such objects, I'll work on that. (and
other points I didn't mention)

Just one point though:

- do we want to scan egg-info directories that are *directly* added in
sys.path ?

  If we do so,  using directories objects would require looking for
the parent directory to create a directory
  object that hold each one of those "top" egg-info directories.  This
seems like a bad idea to me.
  Or maybe a specific global directory object could handle those top
egg-info dirs. Its path would be
  virtual, and it would use "sys.path" instead of "os.listdir()" to
list the elements it works it.
