If webpages supported tls-N, then this seems like it could be cool, but as is, I don’t see what this does beyond what originstamp (and similar services) provide . The tls notary thing others have mentioned here sounds cool, and I hadn’t heard of it. The interactivity allowing for a proof even without the server supporting like tls-n is impressive, if I am understanding correctly!
