Mooix is a multiuser object-oriented dimension (a MOO) layered over top of your favorite Unix system. To the user, mooix looks much like any other MOO. To the programmer, mooix objects look like directories full of files: executable methods, properties, and links to other objects. MOOs have historically had poor support for such things as real programming languages, encrypted logins, multitasking, and editors. Mooix inherits all of these things from the Unix system it is based on. At the same time, it's not wedded too tightly to Unix (e.g., it implements its own permissions system that is much more suited to a MOO environment than the historical Unix system).

Elektra is a universal hierarchical configuration store, similar to GConf and the Windows Registry. It allows programs to read and save their configurations with a consistent API, and allows them to be aware of other applications' configurations, leveraging easy application integration. While architecturally similar to other OS registries, Elektra does not have most of the problems found in those implementations. Elektra includes a library, an API, and commandline and GUI tools for administration tasks.
Eggy is an IDE that includes syntax highlighting, template features, options for compiling and running your code, auto completion, and more. Eggy's distinguishing feature is its support for group projects, which allows users from around the world to connect to each other and work together on a project and see live changes being made. Users can communicate through the chat mechanism, add, remove, and rename files to and from the project, sync files, and exploit other useful features. Eggy supports many languages, including C++, Python, Perl, Ruby, shell scripting, and others.
MrTools is a suite of tools for managing large, distributed environments. It can be used to execute scripts on multiple remote hosts without prior installation, copy of a file or directory to multiple hosts as efficiently as possible in a relatively secure way, and collect a copy of a file or directory from multiple hosts.
