Cool to see but stupid idea, who in their right mind would use this for production?! By using such a "technology", you lose SEO strength due to urls-not-being-like-this.html and even worse, what can stop me from publishing a fake press release on there site/spamming porn and getting that URL indexed? And what are the benefits? To also bring SOPA into this, couldn't I share copyrighted material on someone's site like this? How could they control that?! Besides blocking each URL manually. Just seems dumb. As a concept, cool, but for production.... Yikes?!
