DCOP is an interprocess communication system for KDE versions up to 4 (which replaced it with D-Bus), for more information, see: DCOP on Wikipedia. It is not usable for KDE 4, so it is a pretty dead technology; but this recipe could be useful for people who are still using KDE 3.5.
The code for this recipe displays the title, artist and the album of the currently playing song by Amarok 1.x via Amarok's player service.
You need to install python bindings for DCOP to be able to use the code; on Debian the package you need is python-dcop.
The recipe can be extended in many ways by calling other methods of Amarok's player service, or adapted to work with other KDE applications; you can use kdcop application to discover applications and their DCOP services.
