It was interesting...
But then you started using an API and cut out all the possible server creation that would of been fantastic for people who really want to get into the nitty gritty of server programming. I built a multi-player server in Java from scratch and it was the single best learning experience I had with both Java and Flash and trying to get them to work together. I am a much better programmer because of that experience and because I understood every single aspect of what my server was doing at any given time.
Aside from that, the actual concepts were very well presented and will certainly give some people food for thought!
