Well, Cassandra needs Thrift.  And long-term we'll also need Apache
Hadoop ZooKeeper for lock management, because Cassandra has no way to
lock records, and even if you do a quorum write there is no assurance
that your write succeeded in a way that someone else didn't also
concurrently write a different value to the same row.  :-)

If you manage to get everything into Orbit that we need, we'll be
happy to contribute the code to the JGit project as an optional
storage layer.  It would be nice if it was all housed at the same
place, but the large dependency chain makes it a lot harder to work
