+TODO:
+=====
+
+This is a place to question fundamental assumptions.
+
+Feature Requests
+----------------
+
+1. **Extend address space from 33 bits to 36 bits.** The number of humans who have ever lived
+is estimated to be about 10^11; this is sufficient to handle current requirements but what about
+scalability?
+
+2. **Geolocation.** 16 bits for lat/lon of birth location gives approximately 1 degree of
+resolution on the surface of the earth, enough to narrow it down to a city, but what if that
+city is Beijing or London? Only about 16,000 of those uniform patches will have anybody in them;
+almost seventy percent (except for islands) will be wasted.
