"I'm working at a major university in the US, and have been charged with posting pod-casts of class lectures on the internet. The problem is whether or not posting the videos would allow students to skip class and just download the lecture, instead. I guess the problem is trying to strike the right balance between allowing good students to take advantage of this resource, but discourage bad students from staying at home all the time and watching all the lectures right before the exam."
There's a discussion going over at Slashdot.org. Take a look and see what you think.
