Fair enough. I suppose I consider a cluster to be something that shares
work via a single point of access, not just something that shares data.
I think of "clustered sessions" as "shares sessions" within a cluster,
where the cluster handles work as a whole.

Having different clients connect specifically to one node in a "cluster"
is merely using shared sessions to me. That would kind of be like
calling several servers using the same database a "cluster" because they
share data.

Agreed.
