Appctl is a framework for virtually any server software. It provides a central script called "ctl" which allows you to start, stop, restart, maintain, or query the current status of an application. It is meant as a completely generic replacement for application-specific startup/stop scripts. The project also supplies generic monitoring scripts for clusters, which can dramatically decrease clustering costs.
SrcControl is a new form of package management system. It doesn't have a centralized package repository and packages don't have the actual data for the program it installs. What a package, or "source package", contains is information required to locate and properly download, extract, configure, compile, and install the newest version from the Internet. The whole point is to create an 'add-on' package management system supported by any Linux/Unix distribution. Programs that aren't supplied by a distribution can be easily installed without users having to figure out how to compile the program on their own.
Paludis is a package manager for Gentoo (and derived distributions) and Exherbo. It consists of a core library and a number of console-based clients. Package formats supported include Gentoo ebuilds and kdebuilds (as defined by the Package Manager Specification), the Exherbo exheres-0 format, and various miscellaneous utility pseudo-formats for managing accounts, unwritten and unavailable packages, and packages for which no package exists.
Vamos project allows computers to run software directly from the network, without installations. The software is stored on servers and is centrally maintained without the user's effort or attention. The user just needs to run applications, and the necessary bits are streamed automatically to its computer. The execution of the software is local, allowing high responsiveness and distributed computational load.
