IPFS does look interesting, but how does it provide updateable references? What's the equivalent of "give me today's headlines", which is pointedly not content-addressible because you don't know the content yet?
In the very near future, the entire New York Times archives will be fetchable just by asking for it. Your computer will ask your neighbor for the front page for July 21, 1969, and they'll send it right over.
Yeah-- the IPNS records have a notion of recency, as well as being able to write version history datastructures (e.g. git)
