sure, but I noticed that gs doesn't obey so much security settings (you
can extract text when copy is forbidden, e.g.).

Well, fine for me, as I checked that the encryption mode acts OK as a
postprocessor, but doesn't really interact properly with pdftex working.

What I (we) really need is some batch postprocessor that would add
protection and optimization to the PDF files from pdftex.

Apart from using acrobat's batch mode (which implies windows) there seem
to exist no way to do that (preferably under linux). Wouldn't it be
quite feasible starting from the existing work by R.S. Carmenes?
