Arnie Joris recently created a BigBlueButton extension for Foswiki, a wiki-based collaboration platform.
According to the description on the extensions page,
The plugin will automatically create these meeting rooms on the BBB server, creates a wiki topic for each meeting room (a room named Lotus will be described in topic LotusConferenceRoom) and provides macros to join meetings and see who’s in them
Yet another open source integration using the BigBlueButton API.
