A trick I have used on some of my sites is to open the page you want to stop them from stealing the code in using a popup window, but disabling the menu bars hence preventing them from using VIEW > SOURCE.
<a href="#" onClick="MyWindow=window.open('redirect.htm','MyWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=???,height=???'); return false;">
Team this with a right click disable script on the page and the vast majority of users will struggle to get your code.
I know most people don`t like popups but if you want to disable the whole of the site, have a splash screen and launch a full screen popup from there which will prevent any further popups. hmm, ok, confusing myself now!
