Oh, it seems that I've touched a nerve. My apologies just in case.

[1] says that half of the Debian users participating in popcon have
avahi-daemon installed. Your assertion that "don't camp" is a minority
is off. That's a first.
Second, contrary to the popular thinking here, the world does not start
and does not end with GNOME and x86 along with the CUPS installed.
And while avahi enhances CUPS' usability indeed, it has little
usefulness otherwise.
Third, whatever good avahi does is limited to a single L2 network
segment by the very definition of how it works. This particular problem
shows it BTW.

Easy. You don't understand what the software does (Gene's here), or you
don't need its functions (I'm here) - you just do not install it. You
don't fight with it, you don't try to "disable" it in myriad ways, and
you do not build assorted kludges alongside of it - you do not install
it, simple as that.
