I wrote something very similar, thought not as advanced, srvr https://github.com/MatthewCallis/srvr but this looks much more complex with the awesome plugin system.
I figure most people will want to use it more like Apache though: set & forget & loads at startup.
Don't know if I'd call draughtsman advanced: it's too small for that. Or maybe its diminutive size is a testament to node.js its power for anything related to servers and proxies; I probably wouldn't have bothered if I had had to write a server like this in any other language.
