We made a Bigtop/Juju announcement on the dev list last week  and have been hacking away to address issues that surfaced during the discussion.
We're ready to move forward with the proposal to include Juju charm, bundle, and "cloud weather report" sources in the Bigtop repository.
Commits and an updated PR are incoming... Thanks!
