At a recent Moodle Moot in Kochi, Japan. There was presentation on video recording strategies in Moodle, at which I was one of the presenters. Afterwards there was a discussion with Martin Dougiamus and some others on how we could best integrate video (and by extension, audio) recording in moodle.
We didn't have time to "conclude" anything, so I wrapped up my ideas into a blog post. If you are interested, please head over there and add your thoughts.
