So, to do that, pdfTeX should start to calc document diggest and there should be standard(?) process of signing this value.
how is that one calculated, imagine that in the %! fields you fill in placeholders like hereshouldgosomemagiccode, then one can run a script over the pdf, calculate that magic, and replace the string; maybe this can be hooked into xpdflib
