So it seems that it be fair to say that by reducing the latency, and finding a more
reasonable bandwidth*delay value, the AQM allows non-interactive traffic to
make do with less buffering.  This improves memory utilitization on the
receiver (the viewer), but perhaps more importantly, might it also improve
memory ultilization on the sender by allowing sent data to be purged faster.

Could this reduce the cost of OTT streaming services?
Maybe the savings is insignificant for a small service, but could it be
substantial for larger services?  (there is a media spin to avoid here)
