The author, referring to a Chronicle article, introduces ACTLab TV (aka Alluvium). I installed the demo viewer just the other day to see how it works and was suitably impressed. The secret to this software is that it integrates content authoring tools with shared downloading (a lot like BitTorrent). This puts the distribution of video content into the hands of individuals. So far, only a demo of the download tool is available, though release of the authoring software is expected any day now.
