Filtering software bete noir and DMCA expert Seth Finkelstein has two good posts on his Infothought blog regarding the DMCA, PDFs and reports about blogging. In the first (Making Fair Use of the Report on "Big Media" Meets The "Bloggers"), Seth links to Dowbrigade News, which had noted the irony of a report about bloggers available on the internet not being easily copyable (The Devil Is in the Details):
It [the report] is available as a free download .pdf from the Shorenstein. The weird thing is the extent to which the authors have gone to make sure this milestone article in the academic history of the Blogosphere is unbloggable. Excerpts or selections of the text cannot be saved, or copied and pasted. The document cannot be converted to another format or saved as anything else. The words "Not to be Copied" in 92-point faded-shit brown watermark letters are splayed diagonally across each and every page.
Seth, being smart, knows how to decrypt the relatively trivial encryption scheme used for the PDF. Of course, he also realizes that doing so would definitely violate the DMCA. Seth, being clever, knows that there are often other ways around DRM and provides a couple of means of circumventing the copy protection that, arguably, won't get Seth into trouble for violating the DMCA.
In a follow-up post, he goes into a little more detail how the DMCA operates with regard to circumvention (PDF, DMCA, and "Do Not Remove This Tag Under Penalty Of Law"). Once you have printed an encrypted PDF document to a file, which the Shorenstein paper permitted, the only "protection" for the document is the following code:

As Seth notes, under the DMCA, it is plausible reading of the statutes that removing those lines from the code is a violation of federal law.
The report, which discusses the blogosphere's role in the Trent Lott affair is available here: "Big Media" Meets the "Bloggers" [Fair Use Inhibited PDF]. Perhaps someone from the Berkman Center should discuss some of the issues involved with using fair-use inhibited file formats with the Shorenstein Center.
