I like Fred's (and Stanford's) suggestion of dividing things up into modules. I also like the case study approach. And I like the idea of having a technology course -- where you really learn how routers and protocols and networks (different kinds of networks) work. I like it all! I think in later years we'll end up with a much broader group of courses. For the moment, we're starting with a survey and a heavy dose of technology. I'll keep letting you know how it's going (and students will too).
