Jim,

Thank you for publishing this; it's most useful to the Asterisk 
community. Did you make any measurements of voice quality (jitter, 
packet loss, subjective listening tests by a human) at high loads? From 
a brief read at your PDF document, I didn't see anything on this - my 
apologies if I've missed it.
