I'm not so sure.  I keep hearing stories of DoD types showing up at physics
and OPTICS conferences demanding to preview all papers and outlines for
courses.  Invariably several papers are ordered to be withdrawn.  Something
along the lines of "Non-classified but sensitive information."  That's
governmentese for: "We are very impressed with the work you have accomplished.
Especially since you did it without DoD funding or access to Secret data.
However, it is too good and, in the interests on national security, we are
commandeering all of your data and locking it up so it won't fall into
the wrong hands.  If you even think about telling someone else about your
work, we'll lock you up just as tight.  We understand that this has been
your life's work, and you are welcome to come work for us...  Who knows,
perhaps you might even be able to get clearance to see your work again."

I believe RSA fell into that category for a while.
