OIC. Well, if you open up the .pdf in Adobe Illustrator, or some other
graphics app, you could either apply the real transparency effect
(Illustrator), or fake it using overprinting (FreeHand) or some other
standard pre-press trick (rasterize the drop shadow to a bi-level bitmap
and set it to overprint).

That could then be placed and would work belike in Adobe Acrobat 5 (the
Illustrator method), or with pretty much anything (the other

As I stated before, and implied above, if you just place the page using
``pdfpages'' it should view with full transparency effects in Adobe
Acrobat 5---but if you're printing make sure your commercial printer can
handle it (i.e. has a PS Level 3 RIP with in-RIP trapping).
