Very nice intro. I like how you introduce networking layers. It seems you are starting to go down the path of explaining how computers and servers work - and that is certainly daunting. Maybe just stick with networking and introduce more of that and how real world systems (T1 and Ethernet) are just changing voltages at some point - and can be swapped in or out because of network layers. Then build up packet switched messages TCP, Telnet, HTTP

Oh, please, oh please! Get that thing done as fast as you can!

And for once in my life, I'm actually going to sign up for your email list because I want to know when this thing is done!

This is great! Thanks for the link.
