I also discuss the subject in the "Firewall for win95?" thread
where I point out that if cultish subsets of Born Again
Chrsitianity have access to such back doors they should
be investigated promptly since a subset of such cultish
subsets of Born Again Christianity wish to bring about the
end of the world via nulclear holocaust. I expect that
those knowing of the existence of such back doors would
be quick to poo poo such existence and may even be
in such cultish subsets of Born Again Christianity themselves.
But perhaps you are right, Walter, though cheap or free
firewalls are more likely to have such programmed in
back doors or otherwise have entry loopholes than
expensive ones, I bet.
This did not go to alt.conspiracy . :-)
