SpeexComm is a Speex-based, multi-platform voice communication engine meant mainly for gaming. Written in C99, the engine itself depends only on libc, but ALSA and Speex libraries are recommended for audio input/output and voice encoding/decoding. The engine is accompanied by some reference UIs.
NewBG Hybrid IRCD is an ircd based on hybrid. It fixes many bugs from the original hybrid, and adds many new features. The SVS commands can be used to remotely control users' channels, nicks, or modes. Fifteen new flags and many other new commands were added. The K/G line code was completely reimplemented. A proxy scanner with a cache is built-in. Synchronization methods are included. The protocol of the standard hybrid is broken by the new flags. New conf lines are supported, such as Virtual Channels and Nick Aliasing.
