This guy wrote a basic continuation-based web server in Chicken Scheme (which compiles to C). Might be worth a look...

The problem is that i don't really want to write my own web server, I want to write a web app that will run on that server.

So far it seems the plt web server would have been a good option, the problem I have is the lack of tutorials & "get started" type documents or screencasts like you can get for most other languages/platforms/frameworks

SISCWeb? the plt webserver? Something else maybe?

And more importantly - can anyone follow up on mojuba's premis? http://news.ycombinator.com/comments?id=15710
