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