Looking for a virtual filesystem server (like ftp or sshd or NFS, samba) with the following features:

  • open-source
  • cross platform server (Linux/Windows/OSX)
  • linear file versioning (don't need to have branches) - but done transparently, simple, on the save create a new version
  • ability access to the earlier version with some file-name-semantic (like file.jpg;ver:3 or so)
  • support for some level of ACL / permissions

Exists something like?
