WPMU+BuddyPress

Hey Guys!

I´ve got an issue about the wpmu+buddypress integration...

I want to run a installation that the WPMU must be the main installation, it´ll be just like edublogs, but to another segment, and I want the BuddyPress installation with another theme, but it must show the blog posts in the user activity stream... I want that ´cause my WPMU clients wants their users to integrate socially with their blogs, so I thought to do this using buddypress.

So I´m going to use a theme to the main site of the WPMU network, and another theme to the BP network, but I want it keep integrated, is it possible?

Thanks

Cheers!
