It actually seems somewhat preferable to NOT have a node 1 in the
cluster, as that reduces the degree of "magic" that takes place.

That is, events do not "magically" appear on node 1...

I think the "100 series for City A, 200 series for City B" approach is
an excellent one.

Internally at Afilias, we have commonly have set numbers based on the
numbers assigned by our ticketing system.  That way, if you wonder what
replication set 32744 is about, you can search for ticket #32744 and
find all the discussion surrounding why that replication set was created.

Americans might find it convenient to use zip codes as a "geographic
location surrogate" :-)
