The lector is a German expert, still anonymous, but a member from something called "Rote Hilfe" (Red Help), Bad_Brain, have you heard about that section in hour homeland ?
The full report of that lecture will be published on Suck-o in the Hacking &Wardriving section, on the Blogs and maybe downloadable in the download section.
Note : if you all want us to ask questions in your place : either PM FrankB or LaBlueGirl with your questions.
We will try to have everything answered.
