JStart gives the ability to start Java class files (or applets) by double clicking on them from the desktop like any executable program. You only have to assign *.class files to this program. It loads a class file, investigates it according to the Java Sun class file specification, extracts the full class name (including packages), and invokes the main method of that class.
GNU Midnight Commander is a text-mode full-screen file manager. It uses a two panel interface and a subshell for command execution. It includes an internal editor with syntax highlighting and an internal viewer with support for binary files. Also included is Virtual Filesystem (VFS), that allows files on remote systems (e.g. FTP servers) and files inside archives to be manipulated like real files.
NASD (Network Attached Secure Disk) is a prototype next-generation network storage device. Unlike current data servers, NASD provides a simple object interface to storage over the network with cryptographic support, leaving high-level filesystem details to a separate file manager. NASD is intended to provide a flexible basic level of storage functionality and serve as the base of a complex storage system.
