Are you using this at the moment?  My only worry would be that it can
take zeo a while to start up.  do you ever have any problems when it
fails over, as the instances can't connect to anything? (in the past
we've had some issues when error messages like these make it into the
cache layer for some reason)

Thanks,

Miles
