[OT] PDF permissions

[Paul A. Rubin]

Oh LaTeX Gurus:

I'm stumped about how to generate PDF files from LyX that readers can 
annotate.  As far as I can tell, the problem is that several permissions 
(including annotation) are off by default when pdflatex emits its 
output.  I've tried using pdftk and Multivalent to change those 
permissions, but apparently Acrobat Reader uses the more restrictive of 
the permissions on the source document and the permissions added/removed 
by the program (e.g., pdftk) generating the modified output.  That makes 
sense; otherwise I could use it to undo restrictions set by an author.

If I'm right, what I need is a way to generate an initial PDF file with 
all permissions set on.  I can't find anything in the hyperref manual 
about this, and Google (including Google Groups) has failed me.  Any ideas?

TIA,

Paul
