- The Internet Domain Naming System has similar issues. All domains
- immediately under,say, "COM" require unambiguity, but there seems to
- be no real problem there. Also, COM is international in scope, not
- specific to a country.
-
- All that is really needed is a naming authority appropriately
- chartered by commercial enterprise or where necessary, by local
- government. I don't mean to over trivialize the issue, but we're not
- inventing something here. There is plenty of foundation of how to
- manage unambiguous names within a hierarchy.

- or
-
- - it is an ADMD that is "reachable" through interconnectivity and
- "settlement" arrangements.
-
- "Settlement" in this last bullet is an unfortunate aspect of current
- reality.
