This view is a bit too simplistic.  PDF files can contain layers, and
the text that is nicely covered by those black rectangle may still be
present in the document.

In general, PDF documents are not too bad an idea, though.  At least
it avoids the embarrassment of embedded OLE objects which contain far
more information that is actually visible in the parent document (and
I don't think Microsoft's tool addresses this because it would
castrate the document).
