[infinispan-dev] Introducing JGroups scopes

Hey, JGroups scopes [1] have been implemented for a while now and we should think about using them in Infinispan. I looked around a bit to see how we can use scope and satisfy requirements Manik outlined [2]. I think a good idea would be to introduce scope method in InvocationContext? We can start by implementing scope to return hash of cache name where invocation originated and subsequently refine this scope by adding GlobalTransaction and so on. Users, if they really need to scope their calls could do so by attaching additional markers to InvocationContext or smth similar. WDYT?
