I believe John is referring to the queue(s) in the intermediate devices.
While it may be possible to query the queue lengths there (at one point
the MIBs had entries for that) it is still impractical - for one thing,
apart from the next-hop device, the host knows nothing about queues out
there. Heck, the host may not even know about the next hop device - it
could be transparent.
