Is there a way to tie a multisite sub-site to a buddypress group?

Hi, my main site is up at http://www.DrummersDatabase.com

To keep things simple, right now there is only one BuddyPress group on there. However I am going to add another one in the next few months targeted at a niche market within the drum community and I'd like it to have it's own integrated Wordpress site as part of the same network. (ie all new blog posts are posted on the group activity stream, same users on the DrummersDatabase.com forum as on DrummersDatabase.com/subsite

Is there a way of doing this?
