Mirroring databases in v8

I thought I had seen something that indicated that v8 was going to
provide a means to mirror databases without needing all the triggers
etc. I downloaded beta 3 but couldn't see anything that would do this.

My goal is to mirror a database from one server to another, hopefully
from the logs so that there is nothing added to the database. The
mirrored db will be used by the remote server in a read-only fashion and
will become read-write if the master is no longer available. The
transition from RO to RW will involve a reboot of the server as there
are lots of other things that need to be started with different
properties as well.

Is this functionality available in v8 ?
If not, is it likely to be at any stage ?
