You're correct, though there are a few factors causing me to cautious.  The 
first is I'm working on new, untested hardware, and given the complexity of the 
requirements, I'd rather defer to the knowledge of the list re: performance, 
before fully implementing it.  The second is that the NAS'es which will 
communicate with this RADIUS cluster are known to drop auth requests and issue a 
denial if the response is not "quick" enough.  Unfortunately this is a 3rd party 
managed set of NAS'es, and therefore limited in what I can do.

All that said, I have no concerns about FR, its mainly the DB and the 3rd party
