The big problem here is that CIDR is tough to teach, even to  
engineering students. This seems bizarre and counterintuitive, but its  
true. I know this because I've done it. Its really easy to teach  
classful addressing, on the other hand. Other problems include the  
issue that many of the folks teaching have never had to use CIDR in  
real life, textbook age, and, in some cases, lack of mathematical  
preparation and inclination on the part of students.

Scarier: I was teaching graduate students.
