I've been interested for a while now in how "distance learning" technology could be used for something a bit more inventive and valuable than just a hyperlinked textbook, self-grading exercises, and canned lectures. Adrian Miles at vlog 3.0 has an interesting post (linked from title above) about educational podcasting, or "profcasting": use an interview, or conversational, model. I like this; one of my favorite podcasts is In Our Time, from BBC Radio 4.
I suppose I could require each student in a class to prepare for and conduct a high-quality interview of me, or do small-group conversations, on a specific topic in the course. I'd of course have to get everyone's written agreement to use recordings beyond the classroom (i.e., non-commercial distribution rights). OK, time to contact the university lawyers (or get someone else to contact them...).
