There have been many misattributions in the technological world
to include remarks supposedly made about 640K of memory, the number
of computers required for global processing needs, and the number of routers
that would eventually be required for internetworking.  

Perry's claim has the property of actually having been said, so I will archive 
it.

My own speculation is that the security community and its interests are
perhaps a bit broader than than some members wish it were.

If you want to see some interesting physics that represents unexpected
results relevant to communications (and comes from entangled QKD research) 
then take a look at: http://pra.aps.org/abstract/PRA/v81/i2/e023835

There is a human-readable summary at: http://focus.aps.org/story/v25/st7
