D-Bus allows programs to communicate. How is this IPC implemented? Unix domain sockets, shared memory + semaphores, named pipes, something else? Maybe a combination?

A:
Apparently, IPC or TCP/IP:
http://www.freedesktop.org/wiki/Software/dbus
Update:
I mean, multiple IPC methods on different OS's, plus TCP/IP.
http://dbus.freedesktop.org/doc/dbus-daemon.1.html shows that the unix reference edition uses both unix domain sockets and tcp/ip.

This is remarkably similar to the question DBus query. And the answer from Googling was sockets - either for TCP/IP or Unix Domain.

A:
I think it typically uses UNIX sockets. Under Linux, it may use "abstract namespace" Unix sockets, which are the same except they don't physically exist as visible files in the filesystem.

A:
There has been in the past some attempt to use netlink sockets directly from the kernel. More recently (announced during last LPC), some people are working at getting rid of D-Bus user-space daemon and putting D-Bus in the kernel, it will probably also use sockets, but maybe revive the netlink or other approaches.
