Better yet, we should simply morph this into a more general
discussion about properties of mapping solutions.
Presumably, the set of identifiers in the world is going to be very,
very large. Simply pushing a full map to everywhere is going to be
expensive, both in space and time. Pulling has latency issues.
Reducing the number of places that have a full map seems like an
attractive solution, but still leaves the push scalability problem,
albeit with one less order of magnitude of an issue. For the places
that have only a cache, how do you deal with cache misses?
What's the right approach here? Let's have a conceptual discussion
and leave out the mechanisms, please.
