unix socket support

Is it possible to use express with unix socket instead of host:port ?

The listen signature just call underlying server listen method, so I tried with:

server = require('net').createServer(express());
server.listen('/tmp/sock', function() {
  fs.chmodSync('/tmp/sock', 0777);
});

But then when, through nginx, I try to access a page, express crashes with the following error:

[...]/node_modules/express/lib/router/index.js:140
  var search = 1 + req.url.indexOf('?');
                          ^

TypeError: Cannot read property 'indexOf' of undefined

Ok my bad … it seems rather logical to use http instead of net. Now perhaps we need a note in listen documentation to mention that socket are also supported ?
