I believe they still use the MAC address? If the master node changes, the number could suddenly start at a different block, causing massive performance impacts. If they're purely sequential you can as well use a 64 bit int.

What massive performance impact? You'd have one extra IOP, total, as it loaded the page for the new mac address, and then it would carry on as normal. It would be no different from when a sequential ID crosses a page boundary.
