It doesnt mean that their system is secure. But it does mean that they are
not issuing invitations to be hacked.

	Well, I'm impressed. But that doesnt mean that the network I am
writing about is the same network I am posting from. So I could, if I am
careless, compromise a work network while posting from home.
