[Sheepdog] VMs outside cluster - HA

I'm currently testing Sheepdog with VMs running outside the cluster. The 
gateway node used to connect to the cluster is a SPOF in this scenario. 
I was wondering if it could be solved by accessing the cluster through 
load balancers (virtual IP address)?

Does it make sense to balance new connections over the cluster or is it 
better to select one active master node?

What happens if a gateway node fails. Connected clients would be 
redirected to other nodes. Does it have any impact to the clients?

What happens if additional nodes join the cluster: does Sheepdog 
re-balance existing data objects?
