For the past two years, I have actually been a founding partner in a real estate educational company that is leveraging online learning management systems for courses, so this is something I am particularly interested in. And I think the access to AHA conference sessions online is one of the best resources I have for learning, personally. I often stream sessions on a large monitor when I am brewing and have a little mini-library of conference handouts that I browse through often. I'm so thankful for the work the AHA has put into making these available. When it comes to courses, though, users are going to expect a more concise and concentrated agenda that has specific outcomes involved.
From your comment, I think you are speaking of doing a live webinar hosted by the AHA, which could be interesting. It could also be interesting for the AHA to sponsor course creators to produce on-demand content that translates the conference sessions into a specific course that homebrewers could access when they are available. In the project that I am working on currently, we are using this approach to create the content, while additionally having the course creator available on a weekly schedule and having them host an online 'coffee hour' so those who went through the course can ask questions and get a live response.
There is a wide range of ways to facilitate learning and conversation and I would be very supportive of any efforts that can build on those opportunities.
