Subject: Radio Tracking vs. Spying

Dave,

One might wish to consider whether similar technology could also
be used (or is being used) to remotely monitor activites on, for 
example,
individuals' PCs, from outside their homes and businesses.

Such has long been a concern of intelligence agencies (helping
to spark TEMPEST specifications) but technological developments that
may simplify such surveillance, perhaps extending its practical
reach to additional parties, must be taken very seriously.

Given the sorry state of privacy protections in the law and the new
"we don't need no stinkin' court orders" attitude in some quarters
-- plus nosy neighbors and prying competitors -- enthusiasm about such
devices should be taken as a very serious warning as well.
