Unless you use UUIDs it's hard to guarantees name uniqueness. For instance, if there was a JGroups protocol which - before joining - sent a broadcast to all members, asking whether the name it picked was unique, and then joined, it would still not guarantee uniqueness. For instance, if we are in a partitioned state, then a name picked might be unique, but when a merge ensued later, we might discover that some other member in a different partition has the same name.
