Another view of these numbers: at some point rather soon we may be
confronted with the issue of how to address many many tiny entities
(nanomachines etc).  The ip6 address space allows for 10^11 addresses
per cubic millimeter of the Earth's biosphere from sea level to 10km;
so assigning an ip6 to each nanite is a possibility. Getting the
nanite overlords of one planet talking to those of another may
require NAT, though.

(Back of the envelope calculation, YAddressCountMV, etc)
