A distributed version control system. With gitsync-nncp, can be used over Asynchronous Communication.

gitsync-nncp is a tool for using Asynchronous Communication tools such as NNCP or Filespooler, or even (with some more work) Syncthing to synchronize git repositories.

Since Filespooler is an ordered queue processor by default, it normally insists on a tight mapping between the sequence numbers in job files and execution order in a queue.

You can use gitsync-nncp (a tool for Asynchronous syncing of git repositories) atop Filespooler. This page shows how. Please consult the links in this paragraph for background on gitsync-nncp and Filespooler.
