Subject: [*] AutoGuest.hqx 

One of the most common questions I get (just after the -903 from AESend) is
"How do I get rid of the linking password dialog for Guest access?"  Greg
Anderson wrote a marvelously skanky INIT and code resource for doing this.
It allows you to have transparent Guest access for Apple Events.  If you
install the INIT, you get no dialogs if guest access is allowed.  If you 
use the code resource, you get no dialogs for that program.

Mind you, this works with 7.x and may break at any moment, but it is currently
the ONLY way to get past the dialog.
