For Christmas, I'm bringing you another DRMNA exclusive! Michael Feilen is the designer of Spark DRM modulator software. If you are a DRM experimenter, I recommend you contact Michael via his site for a demo/trial copy of Spark. It is great fun for testing your DRM receiver setup!I asked Michael a few questions and in response, Michael lays out not only the history of Spark but great insight into the history of of DRM development. Merry Christmas and enjoy!
