Hi John, That is true, I agree with what you have said.
Given enough time and money (read as "dedication") ...almost everything is possible...for the dedicated. Nonetheless, following the same line of thought as above, we should, as designers of industrial strength commercial apps, make all possible efforts to extend the time and money required for reverse engineering, asymptotically to infinity. I was thinking of a contrib that can do this for QooxDoo specfically and JavaScript in general. As far as the case of browser seeing the javascript and so the user seeing it inturn is concerned....in this case, its running in a headless browser hosted inside a GUI window, so inspection tool options, such as "View Page Source", "View Page Info" or "Inspect Element", are NOT available. Will it still be possible for my user to see what is going on behind the user Interface...Am I looking at it too simplistically.... ??
