Building blocks for peer-to-peer applications

This is one of the most exciting pieces of tech at the moment. I think it's the right decision to provide this as a pick-and-choose p2p library and that they're trying to make it transport layer agnostic makes it even more exciting ("making any data not only offline-first but also compatible with post-internet communication infrastructure, such as shortwave, packet radio, Bluetooth Low Energy, LoRa or simply a USB stick"). I haven't yet developed any p2p tool where I saw the need for this, but it seems to me that they really thought hard and well about the problem space and I really want to give this a try some day.
