dl is a file exchange service that allows you to upload any file to a Web server and generate a unique ticket for others to download. The ticket is automatically expired according to the specified rules, so that you don't need to keep track or cleanup afterward. dl also allows you to grant an anonymous, one-time upload for others to send you a file, without the requirement of account management. dl is usually installed as a replacement for email attachments due to its simplicity (though it can be used in other ways).
CODESH (COllaborative DEvelopment SHell) is an automatic persistent logbook for sessions of personal command line work. It records what and how is being done, for private use/reuse and for sharing selected parts with collaborators. It is an intelligent shell that automatically logs user's shell sessions. Sessions are uniquely tagged and stored in local or distributed backend repositories (ASCII flat file or Subversion or CVS based) and can be extracted and reproduced at any time by the user who created the session or by collaborators located anywhere in the world.

Crypt::IDA is a Perl module that implements Rabin's Information Dispersal Algorithm. This is what's known as a "threshold system": a secret is divided into n shares with the property that any k (the "quorum" or "threshold") of those shares (with k <= n) can be combined at a later time to reconstruct the secret. The algorithm should be cryptographically secure in the sense that if fewer shares than the quorum k are presented, no information about the secret is revealed. The module uses Math::FastGF2 to efficiently implement the algorithm, making it suitable for securely sharing and distributing even large files. The Crypt::IDA::ShareFile module implements a file format for creating, storing, and distributing shares created with Crypt::IDA.
