// This configuration leaves express running on ports 3000 and 3030. I need to avoid that. Help!
var server = app.listen(3030, function() {
    debug('Express server listening on port '+ server.address().port);
});
var io = require('socket.io')(server);

var connections = 0;
io.sockets.on('connection', function(socket) {
    connections++;
    console.log('client connected ('+connections+' total)');
    socket.emit('info', { clients: connections });
    socket.on('disconnect',function() {
        connections--;
        console.log('client disconnected ('+connections+' left)');
        io.sockets.emit('info', { clients: connections });
    })
