The concept of a digital notary as proposed by Ferdinand Reinke already exists commercially in a similar form: Surety <www.surety.com> will basically do what you’re asking for. You can either give them the document/web page to sign, or you can give them a hash and they’ll sign it. They publish a summary weekly in the New York Times, so it’s open for public inspection (at least so long as there are archives of the New York Times). [This is obviously a summary of what they do – I don’t want this to be an advertisement!]
I have nothing to do with Surety, other than thinking they’ve got an interesting solution to a difficult problem.

One feedback with an existing solution.
