([*] according to the wiki, firewire and zigbee are the only things using EUI-64. I don't know of anyone using firewire as a network backbone. (obviously, not that you care.) Zigbee is relatively new and similar to bluetooth; will people use them as a NIC or connect little zigbee gadgets to the internet -- well, there are coffee makers, vending machines, and christmas lights on the internet, so as a novelty, certainly. How many bluetooth devices are running IP over bluetooth? That said, I could see PAN meshes (personal area networks) eating a huge number of addresses, but /64???)
Utility companies utilize Zigbee pretty extensively. So that's millions and millions of addresses right there.
A million addresses is 1/16th of one OUI in EUI-48, and there are 4,194,304 OUIs (after you take out the local/global and multicast/unicast bits). Billions or even trillions of addresses are manageable without needing EUI-64; millions is a drop in the bucket. Still, it's good to know that another link layer -- which people _will_ be running large IPv6 networks on -- is using EUI-64 and that it's not just a FireWire thing.
