I have confirmed that iTunes is not the source of this particular

The Bonjour chatter from iTunes in this configuration consists of
broadcasts of the form UDP mymachine:5353 224.0.0.251:5353 out.
It's not clear I can disable this either without also disabling
access to my printer; other then the method I'm using "Forward to
127.0.0.1" (using deny results in numerous errors in the system
log). My ipfw.log is getting rather large, 102M since Feb 12 (I'm
not logging the common incoming UDP broadcast chatter from other
machines).
iStumbler will tell you what Bonjour services are being advertised
on your segment.
Note that mDNS will always advertise the system's *name* even if no
services are offered. That allows you to use the .local. names
with commandline tools like ssh.
Yes, I use another program but this issue I'm looking at is not
straight Bonjour, it's using port 5353 to send something to the DNS
servers not broadcast addresses.
The services advertised only account for about half of the traffic,
if I have iTunes configured with sharing off why should it be
broadcasting Bonjour traffic, it does not have any services it's
advertising and it's not looking for any advertised services.
