I prefer the terminology "intermediate systems" and "end systems", but not all \
intermediate systems are "routers". All intermediate systems forward packets not \
addressed to themselves, but only intermediate systems that are also routers \
decrement the TTL/Hop Limit.

Isn't that exactly the meaning of "intermediate node"?
Ole,
"Intermediate" reflects the router characteristics, "destination" reflects the host \
characteristics including that these are addressed by the Destination Address. "node" \
is generic and really doesn't convey any interesting information.
