Sharity mounts shares exported by Windows, Samba, and other SMB/CIFS servers in the file system of Unix computers. It implements Resource Browsing, which is similar to the Windows Network Neighborhood (Netbios Workgroups and Active Directory), NTLM, NTLMv2, and Kerberos authentication, Microsoft's Distributed File System (DFS), and manipulation of Access Control Lists (ACLs).
Chiron FS is a FUSE based filesystem that implements replication at the filesystem level like RAID 1 does at the device level. The replicated filesystem may be of any kind you want; the only requisite is that you mount it. There is no need for special configuration files; the setup is as simple as one mount command (or one line in fstab).
