Do they?  How?  Or does using FOs not just make it a little extra work to get at
the semantics?

(As an aside, this is reminiscent of the never-ending question in the
c.i.w.a.html newsgroup, "How do I hide my source?".  And you'll find the
occasional web page with something like

	<!-- Encrypted by Joe's HTML mangler ^&\?+%$@^*()! ... -->

where you have to scroll down 20 screenfulls to see the real source... )

What if those "eyes" belong to indexing robots or other such programs?

So use FOs for copyright protection and/or distribution management???

It won't work.  If the data is visible, it's vulnerable (even if your "FO" were
a GIF -- to take an extreme example --, it could be OCRed).  All FOs, GIFs, FONT
tags, table cells, etc. are doing is making the data a little harder to get at.
And making a lot of people mad. :)

If it's only parts of the source document that contain the sensitive data, just
could use XSLT (as one option) to deliver transformed but semantically rich XML,
with a linked style sheet -- sans the offending material.

I completely agree.  I just don't see how FOs are "high quality structured
data".
