Probably I'm lazy and missed some other announcements earlier, but yesterday I discovered that (most of) the 21C3 videos are available
via BitTorrent. This is nice, and they even have my lightning talk about TPP, although they only show me and not the screen. And I didn't get any sound working, yet, for the .avi-files. The .mp4-files are playing great, though, with mplayer. I can especially recommend the Fnord Jahresrückblick.
