I've vaguely followed this thread, but it seems to me there's two
different use cases for zeroconf, only one of which really is about open

I want it in Ubuntu; I want it really badly. But not to publish anything
out to others, but for the simple function of finding and using other
devices on the local network. Listening, not doing, in other words.

We have right now a printer at home attached to the local network. It
gets its adress via DHCP from a router in the building, and naturally it
gets a different adress each time. On the Mac therre is no problem at
all; it discovers the printer whatever it happens to be called today and
lets my gf use it completely transparently. I have yet to make this mess
work under Ubuntu. 

After two days of frustration (including accidentally killing my ability
to do ordinary DNS lookups at one point - that was fun), I have resorted
to use avahi to find out which IP adress the printer currently has, then
manually create a new printer in the printer configuration to print (no,
for some reason just editing the existing printer giving it the new IP
adress doesn't work). It sure saves on paper if nothing else.

So disregarding all worry about iTunes, just having this enabled as a
passive listenerand setup so that this kind of device detection setup
works would really, really improve the desktop.
