The eLearning Guild has made several archived webcast recordings from their online conference Converting Existing Course Content to e-Learning available for free to anyone who signs up as an associate member (minimum). There are some great presentations about how to go about converting live classroom materials for delivery over the web.

These web casts, delivered by Adobe Connect feature audio, slides and live screen action along with participant text chat. This provides the feel of attending the session live, of course, without the ability to comment or vote in the occasional polls.
