title: JavaScript library for push/comet/reverse-ajax notifications?
body: <p>I'm planning on building a website where you can play (turn-based) games with other people. I need to be able to communicate which moves have been made. I think push-notifications are best suited for this. I've read a little bit about node.js; is that the way to go? Or are there other libraries that will make it easy to do this sort of thing?</p>
