I've had a reoccuring business idea which deals with having TEMPEST glass
enclosure that you can slide a computer monitor into, the system would be a
very simple Plug'n'Play idea that has a large upper portion with a cavity in
it that the LCD/Flatscreen monitor sits in. The bottom of it would also be
glass, TEMPEST-resistant glass, that fits into the upper portion.  This would
be a very inexpensive alternative to the $5 Grand monitors that are only
TEMPEST level 1.  This could be made from between $50 and $200 and would be
modular in the sense that any brand of monitor would fit inside it.

For those of you that are unfamiliar with TEMPEST technology it is an
emissions security specification that details reducing compromising computer
equipment's radiation so that your neighbors can't pick up the emissions and
reconstruct what is being displayed on your screen.  This was a mahor problem
back in the 80's and mid 90's when the normal monitor was CRT (cathode ray
tube). I'm not sure how serious of a threat it is today, but its probably not
completely gone from the tricks bag of the intelligence community.
