Take another look at that eductor.  I'm guessing you will find that the
high energy steam jet is on the inside and the low pressure outside;
just like the case of the augmentor.  That is the critical difference.

Is this necessarily a bad thing? How much volume/mass of air is expelled

I'm not sure how much air/fuel the rotary holds. What if a narrow (2-3" dia) 
but high volume (collected from the airstream and passed through the center 
tube? Would this not assist in exhaust gas extraction through the same effect 
Paul had discussed causing a natural draft? It ought not be too "draggy" 
since the airflow itself would be relatively unmolested in its passage, 
except to the extent that the vacuum effect reduced its energy...
