Activity stream on the front page with autorefresh

Hello,

I'd like to have activity stream on the frontpage (home-center). At the moment I am using this plug in:

http://wordpress.org/extend/plugins/buddypress-sitewide-activity-widget/

It looks great but I would like it to autorefresh (like facebook).

Is there a plugin that would do that? Or is there a way to add autorefresh function to "sitewide activity widget" plugin? Please advice.

Thank you.
