We are pretty darn close. Actually we use "playground monitor" rules.
Most traffic is well-behaved, and is dynamically and equitably
allocated. The bullies are restrained a bit so everyone can play fairly,
and the weaklings get priority treatment to keep those users happy. We
manage game traffic to minimize latency, for example, as well as VoIP,
video, that sort of thing.

It's not as easy as you describe, but nearly so. We still have to answer
the questions when things get slow at times, but more often these days
we're able to point to outside circumstances instead of having to take
the blame on our own network ;-)
