[Aaron] gave the latest on WiCrawl. The focus has been on the UI and usefulness for penetration testing. It's got support for [David]s coWPAtty FPGA WPA cracking accelerator and some UI improvements. Even better, you can grab the WiCrawl module to put on a BackTrack Slax livecd from the project page. [Aaron] passed out some CD's at the talk - I'll update if the ISO gets posted.
And yes, I think I finally recovered from playing Hacker Jeopardy on team MRL. We held our own, but lost on the (LAME) final jeopardy question.
