Dudders spells "Dynamically Updating DNS Duly Embracing RSA SIG(0)" (with some poetic license). It points a domain name to a given IP address using the DNS UPDATE protocol and a SIG(0) signature. It is designed with embedded systems in mind and is especially useful as a dynamic DNS solution for a home modem/router with a dynamic IP.
Lightning Fast CMS (LFC) is a content management system that is easy to use, easy to customize, and fast. It provides easy mass upload of images and files, variable templates for displaying content, variable portlets, a flexible workflow engine, a role based permission system, multilingual content, and much more. Developers can easily plug in their own applications with templates, content types, and portlets, and provide their own themes.
Response is a set of tools to handle automatic email responses, also called "Out of Office", "Vacation", or "Autoreply" messages. Response tries hard to do that the correct way, i.e. not responding to messages that should not be responded to. All of the validation code can be easily modified to suite your needs, but the project tries hard to ship sane defaults. It is designed for many virtual users and multiple mail servers, but works just fine for small deployments. Configuration and response state is stored in an RDBMS.
Munin is a system to gather and graph all sorts of information. You can install a node on the various machines in your network, as well as on a central server. The nodes will know how to extract various kinds of information, such as load average and bandwidth usage, and will wait for the server to request these values. The output is in HTML format. The server can optionally send notifications if any of the values move outside of a specified range (and when they move back into it).

mod_vhs is an Apache 2.2+ Web server module allowing mass virtual hosting without the need for file-based configuration. The virtual host paths are translated from any database supported by mod_ldap or mod_dbd at request time from MySQL, LDAP, PAM, or a system password file. PHP security can be basically auto-configured from the database using this module. Requests are cached by mod_ldap when configured.
