You would have, I know this FAQ is really outdated but still, there
was a DCOP IPC mechanism before DBUS got created and which KDE also
adopted later on: http://dbus.freedesktop.org/doc/dbus-faq.html#dcop
D-Bus is intentionally pretty similar to DCOP, and can be thought of
as a "DCOP the next generation" suitable for sharing between the
various open source desktop projects.
Well, there's actually major difference between DCOP and D-Bus. DCOP was
a solution that was specifically useful for making desktop apps talk to
each other. It's a domain specific solution, it was not something that
would allow communication outside of the desktop session, crossing the
privilege boundary. D-Bus OTOH actually was a general solution, real
infrastructure of the OS, that was an upgrade to the OS itself, not just
another component of an island that a desktop environment was.
You can use DCOP/D-Bus as a good example to underline the point I am
making: it's GNOME's success to have changed the infrastructure of the
whole OS to a level that somewhat standardized IPC is now available
across most of userspace.
