Sticky Main Article

Love the plugin.

Any thoughts on how to make the main article element sticky so that it continues to scroll when there is a longer sidebar than the content?

Here is an example from the NY daily site: http://www.nydailynews.com/new-york/inwood-karate-instructor-fends-muggers-kicks-article-1.2426547

Thanks for your help,

Ben
