In the days when much business was done by telegraph, companies used to
use their own codes, often as much for data compression as for privacy
- sending the word 'rabbit' is cheaper than 'our local wharehouse has
run out of blivetts'. (Kahn in 'The Codebreakers' reprints a very funny
article based on some of the phrases in codebooks such as "The Captain is
insane and has been detained"). Some telgraph companies insisted on
only certain standard code books - giving privacy from the counter clerk
but not the company). 
Perhaps this is the solution => (what does one doe about open codes ?),
encypher mail and give the system manager the key ?
Or does the DES already provide this facilty for the NSA ?
- Does anybody remember the sketch where (?) Dudley Moore (sp?) is sending
a telgram with the word Knorwich in it ? (Knickers off ready when I come home)
