Not sure about using Steg in PDFs but I'm pretty sure PDFs have the built in capability of signing.

While were on the subject of usable stego for legit purposes, does anyone know of any free software that does PDF stego? I've been asked to find ways to forensically watermarking a PDF ebook.

All the tools I've looked at seem to be too much of a pain in the butt for me to see folks using them to hide their pr0n stash or illicit business practices. Passing messages, maybe. Anything out there that you would see as useful? Maybe something that lets you mound a large AVI or something as a drive and lets you randomly add and remove files?

On a side note, can you think of a time when stego is used as something more than a parlor trick?
