Well, I Googled for this last night and found several SDK hings that looked like they ought to be solutions in the $100-1000 range with no further "royalty", though I mostly assumed that when a couple said it.
I was only really interested in "signing" pdf's with a serial number, but most of these seemed do have *lot's* of doohickeys to play with, including what they were calling security, but I didn't look further. I downloaded something that would put any text I wanted at the main points (could pick vertical and horizontal top/middle/bottom separately) on each page, I get to pick fonts, colours, sizes, input and output filenames. It's free and small (360-ish k), but obviously manual. Not too bad for a few or a few dozen at a push. Also seemed pretty quick, a second or two to write on thirty-six pages & rewrite the file. Not fast I s'pose, but not bad. We publish every other month, and I'm hoping to have hundreds if not thousands to send out, but they can chunter away overnight, both creating and sending. Local processor power is probably cheaper than web server power :-) I think we're in a slightly different situation. A book is a one hit thing that's big enough to warrant "stealing" and selling. Each 36 page magazine possibly isn't worth it, particularly if we can add some other corporate gubbins in to make it more worth subscribing that pirating, but I'm sure we'll "lose" some. We already do, our readership is likely to be more than double our subscription level. I expect it'll be sensible to settle for making it difficult rather than trying to cure the problem.
