I have confirmed that iTunes is not the source of this particular chatter in my configuration (Sharing is totally disabled).

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.
