I don't think replication is ideal for creating single clusters spanning
DCs for at least a couple reasons: the replica assignment strategy is
currently not rack or DC-aware although that can be addressed by manually
creating topics. Also, network glitches and latencies which are more likely
in a cross-DC link could result in more frequent and prolonged periods of
under-replication, higher latencies in the controller-broker RPCs, etc. A
better approach would be to set up a mirror cluster - see
a few updates for 0.8)

Also, for your other question on the producer: a producer can only deliver
messages to the leader of a partition.
