Sure, that's my understanding as well, but see the comments at the top 
of the script, and also the way the script carefully checks for a bridge 
connection and avoids using the IMQ device...

Perhaps it's just a mistaken comment, but it implies that he thinks it's 
possible to avoid using the IMQ device...  I can't see how though (I did 
drop him an email, but no answer so far)

THanks for any ideas on this conundrum
