The Farsight project is an effort to create a framework to deal with all
known audio/video conferencing protocols. On one side it offers a
generic API that makes it possible to write plugins for different
streaming protocols, on the other side it offers an API for clients to
use those plugins.
The main target clients for Farsight are Instant Messaging applications.
These applications should be able to use Farsight for all their
Audio/Video conferencing needs without having to worry about any of the
lower level streaming and NAT traversal issues.
The Telepathy project aims to provide a unified framework for all forms
of real time conversations, including instant messaging, IRC, voice
calls and video calls. It uses the D-Bus messaging system to provide a
simple interface for client applications, allowing them to quickly
benefit from Telepathy's functionality.

Calcurse is a text-based calendar and scheduling application. It helps
keeping track of events, appointments and everyday tasks.
A configurable notification system reminds user of upcoming deadlines,
and the curses based interface can be customized to suit user needs.
All of the commands are documented within an online help system.
