A lot of federated protocols (including partially implemented protocols, thinking @-protocol) are being released right now. There is a paradigm shift occurring in the way software development of web apps is done, and we want people to be aware of all of their choices when exploring this new way of building web applications. Maybe you want to build a federated application yourself, but want certain features that some of these protocols don't have. Well, now you know a little more about what's possible in this design space. Perhaps you've already settled on a protocol (e.g. have started building on ActivityPub), but want end-to-end encryption. Well, now you're aware that you can in fact add it in to your existing ActivityPub-based app. For example, there's no reason why Mastodon couldn't use Shelter Protocol to encrypt DMs between users. Shelter Protocol is very lightweight, and can be an add-on to existing apps. Regarding the ZKPP, it is implemented, but like the rest of the code is not yet separated out from that repo. That is one of the next steps we'll be working on, a standalone developer SDK. We are also welcoming early feedback and contributions from those who would like to participate.
