Pysync has both a demonstration implementation of the rsync and related algorithms in pure Python, and a high speed librsync Python extension. The pure Python is not fast and is not optimized, however it does work and provides a simple implementation of the algorithm for reference and experimentation. It includes a combination of ideas taken from librsync, xdelta, and rsync. The librsync Python extension is less flexible and harder to understand, but is very fast.

The Forban protocols are minimalistic to ease the production of other implementations.

The CryptoNAS project wants to bring data encryption to the masses. It provides two packages: CryptoNAS-Server and CryptoNAS-CD. The CryptoNAS-Server package adds hard disk encryption to a file server (running Samba, NFS, DAV, etc.) without annoying its users. The CryptoNAS-CD is targeted at users who want to set up an encrypting file server without bothering about complicated administration issues.
