FYI, here is a crude Connect middleware that provides a JSGI interface: 
https://github.com/pinf/server-js/blob/master/lib/vendor/connect/middleware/jsgi.js

For some reason this particular closure seems harder to understand. I 
had a good understanding of closures yet the JSGI interface took me more
 time to remember and understand. Maybe that is an indicator that it 
combines too much? We are not even talking about streaming or returning 
promises.</blockquote>
