Goal: eliminate as many steps as possible in finding digital
embodiments of your current physical location.

Usecase: you're in the grocery store, you can't find the juice, you
open your "digital embodiment of this location" app, it goes straight
to a map of the store with your location marked, you search for "oj",
it shows you the route.

My thought was that the AP's name would contain all the stuff you
needed from it. Dereferencing would require your own net connection.

A benefit of this strategy is that a provider doesn't need to provide
an open AP.

Indeed that seems to have been one intent - "and also allows
URL-formatted text that may cause web pages or other internet
resources to be presented by the client processing system."

I have to read this and the mDNS spec to understand them.

Wha? Can you say more about this?
