Thats essentially what i am arguing for.
[I think some, not all, of the wireless qos schemes also have similar
scheduling].

My understanding of these wired "datacentre/virtualization" schemes you
describe is they are strict prio based. When the low prio "virtual wire"
is contending for the "physical wire" with a higher prio "virtual wire",
the high prio always wins. 
We just need to make sure this behavior is also maintained whatever
buffering scheme is used within or above the driver(qdisc level).

cheers,
