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.
