Brian Lamb nails it. "This approach is fatally flawed in a number of respects and it will never catch on. For one thing, it is far too cheap, and can never justify escalating technology infrastructure budgets. Worse, instructors and students could adopt this technology with minimal assistance or oversight from instructional technology specialists." Meanwhile, I wanted to comment to David Wiley, but couldn't because his comment system won't let me log in, that he should get in touch with Tony Hirst, which is also doing interesting work with the RSS delivery of online course materials.
