#Four Ways To Do Pub/Sub With jQuery and jQuery UI (in the future)

Between jQuery 1.7 and some of work going into future versions of jQuery UI, there are a ton of hot new ways for you to get your publish/subscribe on. Here are just four of them, three of which are new.

(PS: If you're unfamiliar with pub/sub, read the guide to it that Julian Aubourg and I wrote here http://msdn.microsoft.com/en-us/scriptjunkie/hh201955.aspx)

##Option 1: Using jQuery 1.7's $.Callbacks() feature:

$.Callbacks are a multi-purpose callbacks list object which can be used as a base layer to build new functionality including simple publish/subscribe systems. We haven't yet released the API documentation for this feature just yet, but for more information on it (including lots of examples), see my post on $.Callbacks() here:

	var cartModule = (function(postal, $){
	var cartId = 0,
	cartTemplate = "#cart-tmpl",
	cartItemTemplate = "#cart-item-tmpl",
	cartChildrenSelector = "#cart-list",
	wireUpCart = function(cart) {
	postal.subscribe("cart", "init", _.bind(cart.init,cart));

	postal.subscribe("cart", "item.add", function(item) {
	var member = cart.id + "-" + item.id;

	but this article should at least provide the stepping stones.

	The article will use distribution packages where nesscary. As of 8.10 the
