The situation is that I work for a small college, and we have a student who will legitimately not be able to attend some classes for the next few weeks. Most of our professors use either powerpoint or a smartboard, and so we're shuffling things around so that all her classes take place in only two rooms. We want to set up those rooms to be able to live screencast (with audio) each lecture.

I've seen other similar questions, but they're all more geared towards recording demos. I'm looking for something more like Live Meeting. Any suggestions appreciated.
