BuddyPress.org

Hi all !

Just playing with nightly build wp 3.0 and buddypress 1.2.3.
As BP can be installed on a standalone WP or WP multi-sites, i though i could install BP on one of my WP site letting other sites working as standalone sites.
Apparently this is not possible.
Did i missed a specfic setting ?
Any idea if future release will allow this ?
