Prompted by the recent discussion to research the issue, I've found
     what might be one. Unfortunately) an expensive one!

     Netscape offers a product called the Administration Kit, which enables
     an administrator to do a variety of things like modifying buttons,
     specifying home pages, and other things outlined at
     www.netscape.com/comprod/products/navigator/version_3.0/management/adm
     in/index.html.

     It does not state explicitly whether you can disable the "quit"
     option, but at least it may be something of a start.

     The unpleasant news is that the product retails for $1995.00. It's
     made a little better by the news at
     home.netscape.com/comprod/business_solutions/education/products_pricin
     g/education_pricing.html#what, which suggests that the price for
     qualifying educational institutions is a (mere?) $795.00

     Calling Netscape if you were interested in the product would certainly
     confirm the presence of a "remove menu" option.

     I know of NO ONE who is using this program (kit), but then again, I
     don't know of any people who have said that it's BAD! If the program
     cannot accomplish what you need, perhaps a unified approach to
     Netscape would work (if everyone's needs were similar).

     How do Internet cafes handle the situation? One bar I know has an
     internet kiosk in it where you deposit cash (I don't know how much)
     and then get to browse (though I'm not sure with what browser). I'll
     look at it more carefully when I'm next there and report back.

     Additionally, The Tech Museum of Innovation has been discussing how to
     address user's needs and may have developed a solution by building
     their own browser.

     Hope this helps!
