hi, imho there is a problem with the app.listen at the end of app.js : the config.address is not used !?
But if I write this :
app.listen( port , config.address );
then there is an error with the console.log :
TypeError: Cannot read property 'port' of null
( If I comment out the console.log line , the server starts well on the specified address )
this was fixed in #165
