Taken this as a fact I want to protect my Milonic menu data, which has cost me a lot of sweat, blood and tears to master, against those evil copycats that are just waiting for me to put my pages on the web.

The menu is used in a PHP file. I have tried to scramble the source by compressing it. After saving the page from a browser and opening the saved html page with an editor it’s no trick to retrieve the menu structure. So that doesn’t prove to be an option.
My question is both as simple as simple:
Is it possible to make the data.JS/PHP non-visible for the browsing web user?
