Danny had a very big influence on the split - he had a great
analogy between milk and wine - it was ok for wine packets
to be delayed (they got better with age) but milk was something
else. That led to UDP for real-time stuff, especially voice
packets - yeah, we were doing packet voice as far back as 1975.
