I really want to see the AWK geo-server implementation. I also want to know who the expert AWK programmer was. AWK is cool, don't get me wrong, but I don't typically think of it as a general purpose programming language.
It seemed like one of "I did it because I could" kind of projects. I've used awk to setup some complicated reformatting of text files that I needed cron but I've never even considered using it as a prototyping language. I wonder what kind of ADTs you can build using it and how viable it would be as the backend of a simpler scripting language.
