Frequently you find a speaker who is covering a very interesting topic, but may not quite have a firm grasp on keeping a crowd interested. Public speaking is not a skill that I have mastered, and I feel that the folks that were talking about Sidewinder are in the same boat. Sidewinder is a promising piece of software that Shawn Embleton, Sherri Sparks and Ryan Cunningham are working on. Sidewinder is a fuzzer that uses genetic algorithms to evolve the fuzzed input in order to get the funky data to the place in the code where you want it. The next logical step of their application is to add some software to create exploits once you get to the place in the code where you suspect a vulnerability may exist. Keep an eye on these three, I see big things coming from their collective intelligence in the next few years.
Update I had a chance to speak with Shawn about the Sidewinder application and he told me it was all coded in just a few months. He isn't sure if he will have time to continue development on the application, but I encouraged him to as I feel it is a great concept and could grow to be one of the best fuzzers out there.
