obstacles to doing academic DRM research

Hello friends - I am a newbie to this list, but an old-timer to the DMCA 
topic and its many relatives.  

I am collecting information about researchers who have encountered obstacles 
(legal, bureaucratic, other) on the way to doing research on digital rights 
management (software or hardware based).  

If you know of a case where a researcher has been denied the opportunity to 
research and/or write on DRM, on the basis of DMCA or otherwise, I would be 
happy to know about it.  I am collecting examples of abuses of academic 
freedom endured under the DMCA regime.  I intend to write an article on the 
topic.  Unfortunately, I myself am facing some questionable obstacles to 
researching DRM that have been justified with reference to the DMCA.  I am 
expecting to hear from many others who are experiencing the same problems.

Thanks for your consideration.

Sincerely
