No, The init I wrote is called fix chooser name. At startup it checks the
chooser name and if it is not the same as the one stored in the init,
the init changes it to match. It comes with an install program that
the netadm uses to set the name of the machine to install it on. This
init is of course very defeatable. For one you could take it out of the system
folder. Two, a user could use resedit to change the string to whatever he/she
wants it to be. Some of our people use the broadcast rdev to communicate
back to one another and sometimes change the user name in the process. This 
init at least sets it back to the correct name after each startup. The init
only does its work at startup time and does not hang around. Some people
won't find it very useful but it serves are purposes well. The majority
of our users just do their work (be it word processing or spread sheeting or
whatever) and don't have any idea (or care) of what the chooser name is used
for.

You could use resedit to install the init into the system file so that
the user can't drag it out of the trash.

Anything you can do with resedit so can a user. So no matter what you do,
it can be defeated. You could take resedit of their machine.

Good luck :-)

Send me a copy when you get it done.
