I would speculate that your terminology is slightly more accurate than mine.
I can't help it, but I'm still thinking the terminology in the
replication documentation is somewhat made up.

Hmmm. Interesting. Does anyone else have details or an opinion on
this? The fact that there is something sitting above the servers seems
to be the defining issue of calling it query broadcast.
I'd argue that "Query Broadcast Load Balancing" and "Clustering For Load
Balancing" are both the same replication type: sync, multi-master. And
the problem they try to solve is the same (Load Balancing).
Listing them as two different types of replication... I don't know. But
we should at least clearly state that both are sync, multi-master
replication algorithms.
Anyway, instead of mocking around any longer I'm trying to come up with
a better proposal... patch will follow.
