Dangerous? Yes. At the same time, he built this presentation using two things; Google-fu for open source intelligence, and a background in microcontrollers. "Untrustworthy third parties", as described in the talk, also possess these skills (look up the sophistication of IEDs used in Iraq and Afghanistan if you don't believe me). This guy invested his spare time over a few weeks or months to do the research on this. Again, this is entirely doable by most people. The purpose of doing this kind of security research is to push organizations (the CIA obviously watches the CCC presentations every year) to fix prior security mistakes before they are misused, and to refine better security practices in the future.
