At the official BuddyPress website http://buddypress.org/ They are running a single WordPress installation with BP. However for some of the pages they have prefixed them with /community/ for example: http://buddypress.org/community/members/ not all slugs have been prefixed for example http://buddypress.org/register/
Any ideas on how this has been done and can be recreated as a client is requesting a similar feature for a project. Thanks
