This reminds me of the Overprice Tags project by Benjamin Mako Hill of the MIT Media Lab/Sloan. See http://mako.cc/fun/overpricetags/
Students at MIT, Brown, and other schools labelled the journals in their libraries with pricetags showing the cost the university was paying for each journal. Nuclear Physics A&B <//elsevier.com/locate/nuclphysa> cost $25,888 in 2005.
Similarly, Students for Free Culture have been working on both the Open University Project and the Open Access Project, pressing universities to reform their use of journals. See http://freeculture.org/

Lastly, public universities have been known to disclose the cost of journals they subscribe to -regardless of NDA status- at the issuing of FOIA or CPRA type requests. See http://en.wikipedia.org/wiki/California_Public_Records_Act
