empegify is a networkable system for creating MP3s. It is designed so that you can perform the ripping on one set of machines, the encoding on another, storing the data to a final machine. It features CDDB support and maintainable code. It also includes a simple Web interface for easy monitoring.
The Faq-O-Matic is a CGI-based system that automates the process of maintaining a FAQ (or Frequently Asked Questions list). It allows visitors to your FAQ to take part in keeping it up-to-date. A permission system also makes it useful as a help-desk application, bug-tracking database, or documentation system.
mod_proxy_add_forward.c is an Apache module that adds a 'X-Forwarded-For' header to outgoing proxy requests like Squid does. You can then get the client IP back on the proxied host by setting r- >connection->remote_ip from this header. It's very useful for the common lightweight frontend/heavy backend mod_perl setup.
Perl is a high-level, general-purpose programming language that makes easy things easy and hard things possible. It is optimized for scanning arbitrary text files and system administration. It has built-in extended regular expression matching and replacement, a dataflow mechanism to improve security with setuid scripts and is extensible via modules that can interface to C libraries.
spam.pl reads an email from stdin and creates a complaint mail which it sends to the postmaster and abuse-receivers of the domains that have relayed the mail. It is customizable to prevent complaining to friendly hosts, uses your own complaint mail and is ready to be invoked from within another mail program.
qpsmtpd is a flexible smtpd daemon written in Perl. Apart from the core SMTP features, all functionality is implemented in small "extension plugins" using the easy-to-use object oriented plugin API. qpsmtpd was originally written as a drop-in qmail-smtpd replacement, but now it also includes an smtp forward and a postfix "backend".
MacOS X "bundles"
In MacOS X we have "compound files" which can be navigated like the directory structures they really are. In the MacOS Finder they look and work like a single file, but after opening a shell you can easily see what's inside.

In my experience being a well known contributor to open source projects is indeed a big help. Just make sure that it's projects that are actually relevant to the company.
