Phonon: Internals and Usage

At aKademy 05 I presented a KDEMM version that was able to play back audio
(and 30 minutes after the talk also video). Since then the name has changed,
many features have been added. Also the internals have been reworked a few
times.

This talk aims at developers interested in using Phonon and those interested to
see how it works internally. Some of the requirements for Phonon backends will
be mentioned and the challenges facing the project.
