Wire type plugin

Hello

I'm new here to WP MU Dev so hello all!

I plan on using the Communities Plugin. One thing I would like to be able to do is to have a Wire type feature like that of BuddyPress where say a User creates a Community then their community members could have a Wire section on their blogs and post updates of their activity and these updates would show on their friends pages as well as all new updates showing on the main Community page.

Is there some way to do this now with existing plugins?

Thank you!
Joe
