Hi,

That sounds good to me too.

I have some comments:

  - An interface name may be longer than 4 characters.  But I know we should
    have some limit so I suggest 15 because it's maximum length of interface
    name on *BSD and Linux systems.

  - FYI, there was an attempt to define textual representation of zone id:
    http://tools.ietf.org/html/draft-ietf-ipngwg-scoping-arch-04#section-12

  - Can we have a dot in interface name?  On Linux systems, VLAN interfaces
    have one.  An example in the draft above has "%pvc1.3" (may be an ATM
    interface?).


Thanks,
Tomoyuki.
