Well, Jeff, you are 100% wrong here.  The analogy between a home and a
computer is not in any way shape or form a valid one.  Unless that disk 
that is spinning around belongs to you personally, you can't tell me 
which bytes I can and cannot look at by suggesting that it is immoral
for me to look at bytes without my name on them.  You have been given
a means by which you may deny me access.  If you choose not use this
mechanism, then you have given me implicit permission to look at your
files.  

	If you insist on a real world analogy, try this:  it's as if
someone said, "Here, use my house.  There are other people that I let
use my house, so here are some keys.  Use them to lock up your stuff.
If you don't, anyone else can play with your stuff, just as you may
play with anything you find."  See the difference?  It's not *your*
house, it's everyones' house.
