Leslie Maxfield gave an in depth talk on streaming media in general and webcasting lectures in particular. To see some of the webcasts they have produced with their new Mediasite system, the catalog of public web casts is at http://dmscatalog.caltech.edu.
For those of you who missed the presentation, you may watch the webcast version. If you need help setting up your computer to watch this, please see http://morel.caltech.edu/ms_help.
And if you are interested in a flash version, see http://morel.caltech.edu/demo_flash. DMC does not have a Flash streaming server, so this presentation is not officially streaming. The preparation is handled such that the server only sends out 5 minutes of video/audio content at any time for quick-starting and smooth playback. Pretty slick.
