Frame Buster Buster ... buster code needed

I'm not sure if this is viable or not - but if you can't break the frame, why not just display a warning. For example, If your page isn't the "top page" create a setInterval method that tries to break the frame. If after 3 or 4 tries your page still isn't the top page - create a div element that covers the whole page (modal box) with a message and a link like...

You are viewing this page in a unauthorized frame window - (Blah blah... potential security issue)

Not the best, but I don't see any way they could script their way out of that.

FWIW, most current browsers support the X-Frame-Options: deny directive, which works even when script is disabled.
