I love it. But in the spirit of today's Internet, you should make this message an obnoxious pop-up that requires dismissal with a tiny "X" button that is dark-grey-on-black and placed tactically so as to be the least accessible. The touch target on touch devices should be tiny and slightly off. The pop-up should also fail completely on iPads, covering all the content with a dark overlay but giving the user no way to proceed.
