I have been watching the first couple videos and I have to say that the disc encryption talk from Jacob Appelbaum has been my favorite so far. Not only because Jacob did a very well talk and some AppleBashing but also because the mentioned Roland C. Dowdeswell's cgd for NetBSD as one of the best implementations. In fact all BSDs did do well (besides Apple :)). Here is the link to the torrent.
If anyone has troubles getting it from there I will put it up here. Nice job Jacob! And of course Roland :)
