  As far as I can tell, it uses a master slave relationship.  Clients
connect to the master, and the master automatically replicates updates to
the slave.  When the master fails, the slave becomes the master, and I'm
pretty sure this automatic.  I'm pretty sure that clients have to
re-connect manually, which isn't too hard if you have good error handling.

  I suppose your "...give it a command..." comment refers to the "hsb"
remote-control command?  This command requires a parameter (which I have
not yet figured out), and I believe is used to define the master-slave
relationship.

  Anyone know more about hotstandby?
