It still isn't clear wether you are interested in tracking a very precise piece of hardware or a very precise registration against a server (whatever it is, since you didn't tell anything about it).

Unless I'm wrong, these could be very different things. Could you elaborate?

We are trying to track a specific machine. This ID value will be sent in all communications with our back-end server. The requirements are that it should be globally unique and persist across application uninstall/re-installs. I've added a person requirement to not leave any stray files on the system after an uninstall. My solutions is to combine the Mac address and the serial number to create the unique ID. These are the Apple recommended values based on TN1103. If either or both of these are not defined I may factor in the IOPlatformUUID value, and as a last resort will default to generate a UUID. Thanks to everyone for their input. I still haven't found any more information on the IOPlatformUUID value, so I'm going to assume Mac and serial number are still the preferred methods.
