Right, they are also wanting to tackle advanced provisioning use-cases like pushing bits to nodes. However, the above description means that you still need to provide a management API that would apply and persist configuration changes to the infinispan grid that survive restart (this is what the profile service does). In the AS that's not a problem because Brian's profile service integration would manage all of this. However in a standalone mode you would either have to implement something specific to infinispan, or alternatively find a way to reuse the profile service + clustering pieces in the AS.
