    Thoroughly fascinating. Alex provided excellent depth of technical detail, and I had a great time hearing it again while editing the talk for the FredPod podcast episode recently published. Hear the highlights of the talk via either of the following RSS feeds:

    I would have like to attend this meeting (given my background in security) but I have a window guy coming to my house. :-(
