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.
