Scott pointed you to a change set that I posted to the list to take 
care of doing this. As I said in that mail, it disables:

* Halos
* Meta and Debug menus
* Command keys in world
* Command-dot interrupts
* Debuggers (though notifiers will still come up)
* World menu (from mouse or key)
* Command keys other than editing & cursor in text

What you must further do:

* Remove the programming tools. Though it's very difficult to get to 
them with my change set, to make sure you'll probably want to do 
this.

Code browsers, etc. can go (and will shrink your image). Note that 
this should be among the last things you do, as part of a lock-down 
script.

* Make sure that any text entry fields, etc. have custom context menus 
or disable the yellow and blue buttons altogether.

* Disable the ability to run scripts named at the command line. I 
forget where this happens, but it will probably be in a startUp: 
method. Of course, if you remove the compiler it won't be a problem.

* Depending on what you're doing, you may also want to remove the 
compiler. Clearly, you won't be able to execute workspace code after 
this, so you probably want to wire this to a button that then deletes 
itself.

What you probably also want to do:

* write a script that strips out all the unnecessary cruft out of the 
image. There are a number of entire applications in there (games, a 
web browser and mail client, a web server, etc.) that you probably 
don't need. Then share the script with us because we need it too!

Please share your findings and improvements with the list. I (and 
probably others also) want to ship packaged Squeak-based apps.

Thanks,
