Is the point of the oriface to reduce the amount of
vacuum whatever is at the end of that hose sees?

In a dynamic system, an oriface would be a pressure
loss (or in this case, rise), but especially with
highway driving, we should be dealing with more steady
state manifold vacuum conditions, right?  In which
case, the oriface would just slow the response time a
little bit... almost like acting as more of a
damper(?).

Can anyone explain to me why orifii and different
sized lines are necessary for the vacuum sub-system?

Thanks,
-Damon
