GUID and GUID(GENERATE-UUID) are equivalent. Both generate GUIDs using the same algorithm. I haven't stepped through all of the code but from what I have seen we don't use the MAC address. Instead, we use a combination of the timestamp, some information from the system, and random numbers. I'm not in a position to make an official statement, but I don't believe that the implementation guarantees uniqueness but rather relies on it being statistically improbable that the same GUID will be generated twice. I, too, would be interested in specifics about a situation in which collisions were found. I believe it's possible that there could be a collision but it should be like winning the lottery three times in a row and not something that happens frequently enough for someone to use the word "occasionally". That suggests that the algorithm may be flawed and would need to be fixed.
