Now, I don't know of any way to assign "ownership" to bundles of energy.

One way is to add a unique bit of modulation to each
bundle of wave energy. I am fond of using a TV signal
and observing ghosting on the screen. This, of course,
assumes that the modulation stays with the same component
wave to which it was originally associated.

But let's suppose that the energy which flows into the node from the
left side during the "inhalation" part of the cycle is the energy which
flows out to the right during the "exhalation" part of the cycle, and
the energy flowing into the node from the right exits on the left. So
now we've managed to get energy past the node going in both directions
while maintaining zero power and current at the node and conserving
energy as we must.

This agrees with the distributed network model. Since
there is no impedance discontinuity and no impedor at
the node, there can be no reflections at the node. The
forward wave flows unimpeded through the node as does
the equal magnitude reflected wave. The net energy flow
is zero. The average energy flow is zero.

Anyone who believes there is zero energy at a standing-
wave current node should touch that point on a transmission
line (which just happens to be the same point as the
maximum voltage anti-node).

One must be careful not to confuse the net signal with the
component signals. One must be careful not to confuse the
average values with the instantaneous values.

This can best be visualized using light waves in free
space. Unimpeded EM waves do not bounce off of each other.
