Prepping for Black Hat and Defcon goes well … DNS radio is such an amusing hack 🙂 Speex is very impressive. A small public note — I’m looking for deployment experiences with Scanrand, as I shine it up and patch it for another Black Hat release. If there are any features you’ve added or needed, or if you’ve deployed Scanrand across some absurdly large network, let me know. I’ve written up my own experiences here, but would absolutely appreciate external input. Thanks!
