it's an optimization that will work well when there is only one person using the 
network, and utterly collapse when there is a lot of use.

it assumes that 'high priority' and bulk things only move in one direction, it 
uses more channels, which will cause more collisions with other users and other 
networks.

a fairly typical type of idea to someone who doesn't look at what's actually 
happening at the RF level.
