DryDock is a Web publishing application that implements a development/production Web site pipeline. It codifies an approval process that forces users to approve all Web site changes before they go into production. It is easy to customize for integration into an existing Web development setup, it does no heavy-handed content management, and it's designed be transparent to Web authors. It tracks revisions, issues email notification of changes, and lets administrators instantly know the complete history of any file that has ever been published.
Divmod Vertex is an implementation of Q2Q, a protocol for opening authenticated connections, even through NAT. It allows a user to reliably demonstrate their identity (for distributed authentication) and receive real-time data directly from other users, and provides a mechanism for a user to decide whether they want to expose their IP address to a third party before accepting a peer-to-peer connection. It is byte-stream oriented and application-agnostic. Any peer-to-peer application can use Q2Q to open connections and deliver messages.
Twisted Names is both a domain name server as well as a client resolver library. It comes with an "out of the box" nameserver that can read most BIND-syntax zone files as well as a simple Python-based configuration format. It can act as an authoritative server, perform zone transfers from a master to act as a secondary, act as a caching nameserver, or any combination of these. The client resolver library provides functions for querying all commonly used record types as well as a replacement for the blocking gethostbyname() function provided by the Python stdlib socket module.
