The final concern of broadcasting the lectures is the professor's. By making the lectures available on the web, a professor losses the control over his or her image. On the Internet there is a concern of intellectual piracy. There may be someone out there who is interested in reproducing Wolcowitz's lectures without consent. To remedy this I would suggest additional password protection to the broadcasts, as well as the original password for the course website--this way, professor Wolcowiz can rest easy.
Broadcasting the lectures over the Internet is a true situation of benefits outweighing costs. With lectures on the web, accessible only through a password protected site by students who are enrolled, Wolcowitz can be fully appreciated for his lectures. Students, simultaneously get the full value of the lectures and the tuition money they pay. The fact that Wolcowitz is having his lectures broadcast truly is "good news," and I hope that it will be for many semesters to come.
