I'm happy to see this project joining the Foundation. As an Apache Whirr committer I feel a lot of pain when it comes to testing compatibility for multiple services across multiple operating systems (and multiple cloud providers).
I would love to join the Bigtop team as one of the initial committers an do some of testing work we are already doing in Whirr. PS: having ready to use .rpm and .deb packages sounds really great!
