I would like to see the ability to have SSPR clustered/load balanced to allow for HA or higher load capacity. It would also allow for easier management as we currently just have two nodes with the same configuration settings set on them and a load balancer in front of them. This works but we run into issues if persistence in the load balancer is not setup correctly or if a change is made to the configuration on one node and the change is missed on the other node. This basically doubles the management effort because all changes have to be made in two places each time a change it needed. This would get even worse the more nodes you have to have based on the load you are running.
