My humble opinion on this matter: - Use a /64 on a link where multiple hosts could reside (ethernet, wavelan, ..) This ensures that when one needs to renumber to another provider one doesn't get a smaller prefix. And autoconfigure can work in this setup.
- Use EUI-64 where possible Makes it easier to autoconfigure. But don't hesitate to use anything else if you really want to. It's your /64, *you* have to manage it, it's *your* problem. Also note that at a corporation you might not be the only one managing the network. You might go away for some reason and another person has to do the work then. - Tunnels which will never be native should use a /127 simply to conserve space. And if you really really want to use a /120 on your ethernet, have fun with it configuring all your boxes. This does imply that IPv6 stack implementors shouldn't limit, software _could_ warn though that it breaks stuff. Ofcourse one could setup DHCPv6 or something to serve /120's... Actually, that subnet is your problem, not that of the rest of the world. If it doesn't work, foo on you ;) Ofcourse these are my opinions.
