Some customers want to do this for a simple load balancing solution that
doesn't require additional load balancing hosts. It's not the worst idea
for 2-3 nodes, especially with an asymmetric connection profile (i.e.,
little data in, lots of data out).
I have a preference for active/passive clusters as long as that remains
feasible, since that makes the architecture simpler. But once one goes
beyond that, it's nice to have options.
