Realtime Activiy

Hi,

is this module ajaxified..? if not how can i make it..? so that it updates and displays automatically when anything new is created on the site.
and also, is it possible to auto update time in minutes,hours etc.. like

if a node is created it should display..
"[user-name] created a new blog [title] 1 minute ago"

so after 2 minutes it should say

"[user-name] created a new blog [title] 2 minute ago"

so after 1 hour it should say

"[user-name] created a new blog [title] 2 hour ago"

i think you got the idea .. just like facebook wall.

any suggestions..?
