dashboard/river ajax more posts

how can i make it so that when u look at the dashboard it shows say 20 items, add a button that says more posts and it will auto or ajax another 20 posts, once the river/dashboard has 40 posts on it the next option would be to go to another page with more posts like it has dufault right now, how can i get this going, so basicly it reacts like facebook, i want it so the system can populate more posts without refreshing the page, but once there are so many posts it will force u to open another page......? any ideas? i think mostly everyone using elgg would love to see this a posibility
