Comment: Nothing new at MIT (Score 2, Funny) 218
Nothing new here. The same thing was done in 2005 when I was in the class. It was done by the professor himself and the next day he was able to display the IM conversation two kids were having in the class. One end was encrypted so he didn't think he could be caught, but the other end was not, so the prof was able to display the chat. Basically the chat had something to do about how bored the student was. It was quite amusing.
