I've been working with a new set of software that does precisely that. 1. Publicly available, with the link. 2. Immutable data, by definition is read-only. 3. Users can easily view the root directory and every file enclosed 4. Uses nothing more than a web browser, with no addons. Right now, it does greatly speed up if you use the peer software. http://ipfs.io http://ipfs.io - Interplanetary File System. It does everything you asked for. The current way the network works well for people who don't run the client is that ipfs.io is running an IPFS->web gateway, where you go to http://ipfs.io/ipfs/[hash] http://ipfs.io/ipfs/[hash] For example, I'm preparing to go to a 3d printing convention where the bandwidth is very limited. So I'm hosting a slew of 3d printer files. If you are running the peer software, click the localhost link. http://127.0.0.1:8080/ipfs/QmRBWNHKvz4AmTGN4QyJ4bQMd4fb5vfTdacjkb6PSHsJ2X http://127.0.0.1:8080/ipfs/QmRBWNHKvz4AmTGN4QyJ4bQMd4fb5vfTd... http://ipfs.io/ipfs/QmRBWNHKvz4AmTGN4QyJ4bQMd4fb5vfTdacjkb6PSHsJ2X http://ipfs.io/ipfs/QmRBWNHKvz4AmTGN4QyJ4bQMd4fb5vfTdacjkb6P... So yes, there is a potential download of some software. What does that get you? It allows you to download at the full speed of the network (bittorrent based) and uses DHT for finding local peers. You can also add files in the network, and share by simply copy/pasting the link to whom you want to have the files. Interestingly, it indeed solves this: https://xkcd.com/949/ https://xkcd.com/949/ Ideally, the IPFS team is working on a javascript-only IPFS node, where the webpage itself is self-hosting the IPFS gateway. That would also free up phone clients and more exotic tyes of computers with only browser support.
