I would assume that in an interoperable world, there is no "local
only" object ID. Or, more likely, if an internal ID is needed, it's up
to each host to manage these, and translate when talking to the
outside world.

Also, I'd think that mapping URI to "resource on the internet" is
right -- VWs are internet constructs, by and large.

Americans might object: there is no way we would sacrifice our living
standards for the benefit of people in the rest of the world.
Nevertheless, whether we get there willingly or not, we shall soon
