No, the keyFile is generated ahead of time and is loaded onto each computer 
via diskette or CD, etc.  If you make a large keyFile at the start (say 
100,000 random numbers) you will not need a new file for some time.  If you 
fill a CD with a number of these keyFiles (for example, a different keyFile 
for each month), you could easily go a whole year before generating new 
keyFiles unless you were sending large messages every day.  The keyFile 
should *not* be transmitted but, instead, should be sent by mail or something 
like that.  

The starting number at the beginning of the message tells the decoder where 
to begin in the keyFile.  You can use a keyFile until all the numbers have 
been used once.  After that, a different keyFile should be generated and 
loaded on both computers.
