I have received a quote from a reporter who I've talked to for one of
the articles linked all over the place. He has received the following
statement from the DARPA spokeswoman (703-696-2404,
jwalker_(_at_)_darpa_(_dot_)_mil). It's below. I could not make this up.
I wanted to update you on the situation with the Univ of
Penn. project. As a result of the DARPA review of the project, and
due to world events and the evolving threat posed by increasingly
capable nation-states, the Government on April 21 advised the
University to suspend work on the "security fest" portion of the
project.
