NUI is a GUI ToolKit intended to work with SGI's OpenGL API. It is similar in many ways to GTK+, Qt and even Win32, but with many enhancements in order to make it an easy and yet powerful tool for cross- platform GUI programming. It is currently developed on platforms supported by the NGL framework.
MatrixSSL is an embedded SSL and TLS implementation designed for small footprint devices and applications requiring low overhead per connection. The library is less than 50K on disk with cipher suites. It includes SSL and TLS client and server support, session resumption, and implementations of RSA, AES, 3DES, ARC4, SHA1, and MD5. The source is well documented and contains portability layers for additional operating systems, cipher suites, and cryptography providers.

It has zero runtime configuration and connections are specified via a URL scheme. A modern object-oriented API is provided. Libzdb supports MySQL, PostgreSQL, SQLite, and Oracle.
ReplicaNet is an object oriented C++ library for developers of applications that require a stable and low maintenance middleware solution to networking. Any project that is designed to use a network of machines, such as multiplayer computer games, need to very carefully consider how to approach the design problems associated with networking. It includes support for binary difference patch creation and delivery, backend availability and TitleID verification, Internet CD/license key verification, NAT detection, advertising and querying of sessions, user accounts, friends lists, game invites, chat rooms, persistent data storage, and statistics and ranking.
