Jquery infinite scrolling up plugin

Question

We are building a web application, with the ability to send messages to other users and we've chosen to implement it the Facebook way. Meaning, a div with a fixed height, scroll bar of the div is at the bottom when the page is loaded. And when the users scrolls up we get the older messages with ajax. (Check out the facebook message app)

So does anybody know a good and stable jQuery plugin for infinite scrolling up? I have found plenty plugins for infinite scrolling down and lazy loading. But none for scrolling up.

Thanks!

Edit: 16 April 2012 Made my own jquery plugin for this.
