I just can keep on telling you: it does work. Even if this particular example doesn't do the job: Exporting from InDesign does. I sent Adib a PDF, that clearly shows this in my opinion. Evince however, cannot display it and displays a semi-transparent black box instead. Curiously, the semi-transparent box that _is_ in the document is displayed without the transparency :D
Not to be a wet blanket, but the PDF specification doesn't provide for filters at all; the specification is publicly available, so you can verify this yourself. What you're seeing for the shadow here appears to be a high-resolution (but very compressable) greyscale image. (It's more evident on the text, where the shadow image is not as high-resolution for some reason.)
