What does this give us that Solaris Cluster, RedHat Cluster, DRBD etc..
doesn't give us? I am not trying to be a poison pill, but I am just not
seeing the benefit over what solutions that already exist. I could
probably argue if I had more time, that this solution doesn't do
anything but make us look like we are half baked in implementation.

If the real goal is read-only slaves with synchronous capability, then
let's implement that. If we can't do that by 8.4 it gets pushed to 8.5.
We already have a dozen different utilities to give us what is being
currently proposed.
