Great presentation on Opencast, an open-source project aimed at building a technology infrastructure and community sharing best practices around lecture/event capture, processing, archiving, distribution, and effective use of podcasting for teaching and learning. Mara Hancock talks about the importance of Opencast in a post about the planning grant. 

The Opencast community appears to be organized around many of the same community values as the Sakai and Fluid communities. In fact the Opencast software is being developed to work with Sakai and to use Fluid. In the presentation they talk about how the application is architected so that it could also be run standalone or integrated in other eLearning environments like Moodle.
