1. You're absolutely right that IPFS alone isn't a good way to guarantee durability. I think you'd need a second level of archiving done in bulk. Thousands of books collated into various torrents that people can help seed. This has already been done for LibGen. IPFS does provide a common hash space for everyone to rally around, and does make it easy to download single books. It's also easy to speed up downloads by using an IPFS gateway - the actual protocol is slow. I don't expect most users to actually pin files or anything. 2. Well, users and librarians need some way to find each other. That's true in any system. And that communication medium can allow certain kinds of attacks. (website on the public internet, word-of-mouth, Telegram groups) If all someone needs is an IPFS hash of a recent library metadata DB (a SQLite file), any way of communication will suffice. I think this approach allows for centralization (sure, keep a website up as long a the authorities don't care) but also gracefully allows for all manner of de-centralization (use any of the above methods to distribute the metadata DB). 3. Any many-to-one system with curation (librarians) will have weak points. The idea is you can set up upload portals across any communication medium (a regular website, a dark-net site, a Telegram group, email) - and the libraries take care of collating the information. The social grouping is what matters more (libraries vs uploaders vs downloaders) - and we want to make it tech agnostic and, therefore, more resilient. This system will be stable I think, for two reasons: 1. Network and branding effects will naturally create a few big libraries. People will use the familiar, useful libraries. See how few torrent search sites took up the bulk of traffic, back in the heyday of torrents. Most users will probably use a website, and the ones that are easiest to use will probably get the most traffic. 2. The resilience of the system is necessary only once in a while. A set of libraries will emerge, there'll be enforcement actions and they might break apart, and then new ones will pick up their pieces (easily bc the metadata and content is open). So we want to provide the open-ness for this to actually happen.
