Double-spacing a PDF output doc from a structured Frame book

[Bob Williams]

Hi All,

This may be one of those 'Well, if I KNEW which menu and function this was -
I'd have already done it myself' questions, but...

Wondering HOW to simply double-space my PDF output doc (from a structured
Frame book) - so that our writers can more easily make mark ups on the
hardcopy. They write - we production wonks put their stuff into the frame
books. (We like it this way - less chances for them to screw up the frame
files.)

 - NOTE: As our structured Frame books are driven by fairly complex
templates (customer provided and managed), I'd rather find a way to simply
double-space the PDF from Acrobat or Distiller(?) rather than trying to
monkey around in the template (ugh).  Or, is there a way in Frame that
before I generate my .PS files to Distiller, that I can selectively invoke a
double-spacing of the output?

Thanks in advance for taking the time to read this - (bowing lowly and
respectfully) oh great oracles of framemaker / acrobat / distiller knowledge
bits.

Regards all,
