A password to be used by a human ought to be something that has all of 
these features:

1. provides the level of security demanded by (or expected from) a 
reasonable--not paranoid--system admininstrator

2. be a word or phrase someone can remember and does not require carrying 
it around on a piece of paper

From the passwords I saw generated below, your program will be good for 
someone in your very special situation, since you would have to carry 
around a list of passwords of your own, rather than a machine's, 
conception anyway.  I don't recommend that sys admins subjugate their 
users with such passwords however.

At any rate, the rapid advances in biometrics (doing security by looking 
at finger or hand or retina scans or some unique identifier on the body) 
will make the weakest link in the security chain---passwords---obsolete, 
as that is the wish of both users and sys admins.

On 9 Dec 99, Nimrod Alonzo Abing was found to have commented thusly:
