I know that people have been noodling over this idea for a few years now. The idea is to create a timestamp combined with the hash of a document. Why would you do this? For one thing, it can establish proof that you created the document, as no other person could have the same document with an earlier time stamp. But the WIPO application costs too much to use (CHF 20 ($21)) to be useful for things like development chains or message webs. And the cost, being what it is, also undercuts free content by creating an expensive overhead to produce any volume of free content (the type of barrier I called 'high bar' in this presentation in 2004).
