I can't help it, but I'm still thinking the terminology in the 
replication documentation is somewhat made up.

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.

Regards

Markus
