It is actually easy to add this kind of support for zookeeper driver. For now,
we monitor sheepdog nodes by zookeeper like this

/membership/[ip1:port1, ip2:port2, ... ]

but if we add a cluster id to it, then it will look like

/cluster_id/membership/[ip1:port1, ip2:port2, ...]

So one zookeeper cluster can monitor multiple sheepdog clusters.

And there is no reason we can't do this.

But probably it is hard to do the same for corosync driver.

You can file a bug for this in
