Lets take a fun game. How about all of Atari 2600?

Ok.. This is remote, across all the machines that have that IPFS hash. In other words, its not local.
(in console) ipfs pin add QmacAqRVhJX9eS7YJX1vY3ifFKF9CduDqPEgaCUSa4x5xb
Now its local!
Or lets do something more than a game... How about Node-Red in browser(PageNodes)?

EDIT: I had the point in my head, but didn't put it down here. In other words, we already have this technology, and not using buzzword-bingo like "Its the interwebz but with blockchains!". These links are direct proof that it not only exists, but is working right now.
And in reality, making a type of blockchain in IPFS would not be hard. It's an immutable data structure, with append-only characteristics.
And, I also am partial to IPFS, primarily because it feels like a proper IETF-internet scale project. ZeroNET looks prettier, but.. throw away. Again, some subjective feel there, but IPFS feels elegant.
