I made Redwood, a general purpose p2p/distributed database (and blob store) with pluggable merge algorithms (including some cool CRDTs, like what @josephg is working on).

Turns out it makes for a great self-hosted git solution, so I made a git remote plugin that allows you to interact with it using regular vanilla git commands: https://github.com/redwood/redwood/tree/libp2p-connectivity2...
