Have TED talks running in the background (I'm beginning to see TED as more useful these days, it's not about new information, it's about getting a feel for how people are communicating the issues).  Interestingly, in Gates' presentation (the one where he releases the mosquitoes) he describes briefly the idea of the video-recording and migration of teaching material as resources, right up to the idea of allowing for a published set of DVDs (DVDs, seriously?) which would represent the best-of-the-best lessons on a topic.
