"Audio and video versions of F-Secure Corporation’s Data Security Summary for 2004 are now available. Video is available as a Real Media stream here: F-Secure 2004. The MP3 is available here: 2004-wrapup.mp3 

"Speaking about MP3’s…we find it be really handy to listen to data security lectures, radio specials and interviews on our iPods or in our cars while doing something else. Places like ITConversations even have separate series for security-related audio. Also lots of the Black Hat Briefings lectures are available as audio (but you do need a Real-to-MP3 converter if you want to take them with you). And Vmyths has great selection of MP3s available (but you do have to dismangle the M3U files to get them)."
