In security, actually in all issues of discussions  (not to say politics 
etc.), one could take
different standpoints. But one should also consider IMHO the "reality" 
in the different
scenarios. Here in security I suppose one should take into accout the 
nature of the particular
applications, the quantity/quality/value of informations and  the users 
concerned, Anyway,
in practice there could barely exist "one thing fits all".  Many issues 
are "probable" but
the vital question is whether they should be seriously considered "in 
practice".

Certainly I could not claim that I am unbiased/objective in my 
standpoint towards my own
software, But I simply can't believe that Hallam-Baker's argument is 
"realistic" in the present
context, since the output sequences  of the software are highly 
dependent on the sources .
There is an enormous "variability" due to the different books and their 
starting points, so it
can't be the case that something e.g. of the genre of PI could ever 
result with any "real"
probability. ("Theoretical" probability is of course a different matter.)
