#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:

  * Idea from Scott Gonzalez
  * to use, place attributes on an already-functional anchor pointing to content
    * that should either replace, or insert before or after that anchor
    * after the page has loaded
    * Replace:	<a href="..." data-replace="articles/latest/fragment">Latest Articles</a>
    * Before:	<a href="..." data-before="articles/latest/fragment">Latest Articles</a>
