People who The question is how feasible is it for an average electronics engineer to install the basics needed. Slashdot Nov 99: "New Scientist has an interesting article about a new toy we will all want. It's a card that plugs in one of your PCI slots and allows you to scan the EMF spectrum and read your neighbours terminal. In about 5 years you might be able to get one for just under £1000. (Modern Tempest Hardware costs about £30000) " http://slashdot.org/yro/99/11/08/093250.shtml > setting up all the fancy equipment necessary to do it.

Personally I work on the basis that taping of 'phone conversations is straightforward and inexpensive. It would be nice though to be able to use a computer with _reasonable_ security where you know that a 'phone conversation may be taped. > > And once you believe that you have taken care of RF shielding, you can > start to worry about optical VHF leaks from CRTs: > > http://www.cl.cam.ac.uk/~mgk25/emsec/optical-faq.html Again the question then becomes how feasible is it for an average electronics engineer to set this up. From which I can assess if I need to take any action. GSO PS A quick plug for the other item on my 'OpenSource the computing environment for Legal work' wish list. A document processor that numbers paragraphs - not as in numbered headings, but a straightforward 1..n of each paragraph down the left margin (e.g. might include numbering of section numbered paragraphs quotes etc). Some groff documentation mentioned that a macro could be created to do this but nroff/troff reference books appear to be on the almost extinct / very difficult to locate list at this point in time ;) __________________________________________________ Do You Yahoo!?
