[ih] Baran and Davies and respetive roles in Apra design

+ bob kahn

bob was a key player in the design of the IMP and the ARPANET

Paul's principal conceptual ideas related to packetization (message  
blocks) and hot-potato routing, I believe

Donald Davies had a multi-node idea but implemented only one node  
owing to funding limits. He or his team
via Roger Scantlebury influenced the ARPANET design be convincing  
Larry Roberts to use 50 kb/s circuits
rather than 2.4 kb/s circuits.

Donald also contributed the term "packet" into the literature.
