Also: 1. "Nodes in the cluster topology are identified by a unique, persistent identity"
How does this translate to the host-name/IP? Several TC-customers have had to write a map that translates the "common name" to the "terracotta identity" to describe the situation to others interacting with the cluster. It would be good if this could be completely avoid. 2. Another problem several customers have had to solve is identifying a delta between a "specification of expected cluster Topology" and "current cluster Topology". e.g. I expect the following 10IPs to be present in the cluster. Any delta vis-à-vis the topology requires some programmatic action. Is there any treatment to make that easy... 3. "Clients need to change behavior when the cluster is no longer able to service operations: (a) Kill themselves (b) Resume ongoing operations locally by for example switching from a clustered cache to hitting the database directly " What would it take to an additional outcome of reconnecting to the cluster a possibility upon cluster service operations resumption. (with presumably state initialized to current L2 state).

Is it really necessary to test that instrumentation is active or are people interested to know about DSO being active. The latter is already possible through the "tc.active" system property that is set to true when DSO is active on a JVM.
