I had a math teacher that did this. He had a netbook running Fedora and would use it to record audio and the overhead screen during classes. Since most of what he wrote up there were proofs, it helped a great deal. Last I heard, he and some other people (he's more of a CS guy than anything), were working on some software to stream the classes while in progress, as well as allow interaction from students not physically present.
