This is usefull for locking down the image for UI based applications
(disabling morphic halos, ...) - you can take this as a base to build on
own customized locker. Especially the code for disabling the Command-dot
interrupts may be usefull. But dont forget to include a backdoor for
yourself. 

You can write a simple login dialog which is either displayed when you
save the image or you use the #addToStartUpList: methods to get informed
about image startup. Have a look at senders of #addToStartUpList: and
#addToShutDownList: in your image.

Typically you will send these messages in the class side #initialize
method which is called when you load a class into the image.

Also have a look at: http://minnow.cc.gatech.edu/squeak/518

Hope this helps
Bye
Torsten
