Having anything but a string be the base doesn't lend itself well to reuse. The JON team needs to define what the aggregate management views are, and what needs to be in the logical ServerConfig view to support this. Having the following seems like a no-brainer: String serverId; - unique within management domain, defaults to hostname String[] serverAliases; - non-unique aliases GUID serverGuid; - supposedly universally unique. The only question is permanence of this value. Could certainly be generated if not found and reused if found. With jdk6 you can get the hardware mac address as input for this.
