Most of the software I talk about, I comment during my talks, is banned at schools, colleges and universities. Skype is a good example of the latest item to incur the wrath of administrators, ostensibly because it eats bandwidth. I would be interested, though, to hear what sort of arguments cross the desk when university officials are meeting with telco representatives. As for the bandwidth, "Skype works over dial-up. How much of a bandwidth hog can it be if it works over dial-up?"
