Why would you want to subvert the idea of opensource by doing this?

It is possible; a quick Google reveals 
http://www.linuxquestions.org/questions/linux-software-2/add-copy-protection-to-pdf-840725/
but it is not possible to prevent anyone from changing the source code 
of their reader so that the DRM does not apply.
