Well, clustering is just a general term for putting several things, say,
computers, together to a common cause. If you cluster a database
system, you need some way to distribute the incoming requests across
the machines, which you can either do on the network layer or on the
application layer. Sequoia does the latter. But I don't see
any "broadcasting" in there as a defining quality.
