Whittling away the DMCA?

The Copyright Office issues a ruling specifying six exemptions to the anti-circumvention restrictions of the Digital Millenium Copyright Act. Among them are the use of film & video clips by professors of film & media studies, and "computer programs and video games distributed in formats that have become obsolete and that require the original media or hardware as a condition of access."

The ruling is otherwise notable for using the word "dongle" in an official government publication.
