Neat use of web torrent. Now if only we could do it with live data instead of persistent data, have built in encryption, and anonymize the peers we'd have the perfect decentralized internet :-)
You mean something like this? :)
Where is the anonymity? It is unreasonable to use TOR in my opinion because despite being only a few exit nodes, it's not truly P2P then (and therefore can be slow). Tribler tried something similar. Someone needs to build an onion router of peers without defined relays or exit nodes (think of it as everyone-is-a-relay TOR, it's one of my future ideas[0]). This will speed things up substantially and can definitely work when you don't have the limitations of TOR like working w/ all TCP connections (e.g. HTTP). Maybe they could make every ZeroNet node a hidden service, I dunno.
Also, I have researched a lot about plausible deniability of publicly available yet distributed data. I have never seen a system that stores public data without them (clarity edit: node runners) being able to find out whether they are storing a piece of something they don't like. I started a thread about it on the Maidsafe forum recently [1]

From what you've described, it seems like i2p would satisfy the requirements of your first paragraph and Freenet would satisfy the requirements of the second. Both of these networks have been around for over a decade, so they're not as in vogue as newer projects.
I have only slightly looked at i2p, but sadly appears the only impl requires a JVM. I have researched freenet and it does not appear to provide plausible deniability for public data (sorry on mobile and can't link easily).
