That's what I said above in the "before you ask" post about MDB singletons.

Let's say you have 26 durable topic subscriptions one for A, B, C, D, etc.
Then you create 26 MDBs to process those messages (single threadedly for each).

In a cluster you put the MDB in deploy-hasingleton or use some other
mechanism to distribute them across the cluster but making sure the MDB
for clients beginning with "A" only starts on one node.
