The web may be *forced* into using something like "visual
cryptography" in order to get around "clickjacking", whereby
the user is tricked into clicking on the wrong button (or the
right button for the wrong reasons).  It's getting harder &
harder for a web site to know & guarantee that what it thinks
is being displayed is actually what a user sees & is agreeing
to.  See Dan Kaminsky's recent DEFCON talk for more info:
