So I've got some travelling to do the next couple weeks, but I'll try
to find some time to read up on some QoS literature and determine the
right way to balance between the queues. I'm concerned that doing the
queuing wrong would incur too much delay on the low prio traffic
(since it would be penalized like 3 or 4 times through the circuit).
