As an aside, this is a concept which - totally independently - was being
developed by some folk in the space communications community in the early
1970s (attached). "Block" telemetry subsequently morphed into
"Packet Telemetry" and "Packet Telecommand" around
1976 and has become the underpinning of most current international space

These space communications protocols have now re-converged with
Internet history and provide a platform on which we are developing
the "Interplanetary Internet":
