ls-fuse mounts output of ls utility as read-only pseudo filesystem.
Purpose of ls-fuse is similar to lsfs project or lslR plugin for midnight commander. But the main idea was implementation of native tool with SELinux support.
As in Pretty Good Privacy, this is a Pretty Good Incremental Backup tool. Inspired in rsync, jnSynch provides a basic file synchronization engine written in JAVA and so executable from either Java-compatible computer.
