How about at least authorship? Isn’t there scope to include in HTML5 a standardised means of indicating authorship and providing some kind of non-http link to the author, e.g. a digital signature (that only the true author is able to corroborate).

Future business models are more likely to be about the users making deals with the author (paying them directly), than purchasing copies or licenses from authorised resellers.

Obviously, with (free) software, there is a lineage of authors and teams thereof, but each deriving author can indicate the authorship of the work they built upon as well as their derivative – thus enabling the entire provenance of the work to be traced.
