Wonderful approach! I would just change it to work with notebooks instead of PDF (to include the data and the algorithm and make replication easier) - through the notebooks could certainly generate PDFs. Then it would bring into publishing the problem of replicable builds: the PDF would not be very helpful if the MD5 didn't match the published signature! The field seems ripe for disruption, with a new model for scientific research and publication.
