D-BUS is a message system, a simple way for applications to talk to one another. D-BUS supplies both a secure system daemon (for events such as "new hardware device added" or "printer queue changed") and a per-login-session daemon (for IPC among user applications). The message bus daemon is built on top of a general one-to-one message passing framework, which can be used by any two apps to communicate directly without involving the daemon. D-BUS can even be used for secure IPC across an intranet or the Internet. An objective of the D-BUS project is to address the IPC needs of GNOME, KDE, and other desktop applications, but it's by no means limited to this role.

This talk presents the technical details of D-BUS as it currently stands and discusses its importance to Linux-based operating systems.
