The people at Esware have
added Zeroconf support to
ifupdown package
. With this, you can easily configure your network devices
to use Zeroconf detection, by using:

      iface eth0 inet zeroconf

in your /etc/network/interfaces file. I wonder what other
distros might be doing for this. For the time being, I asked
à lvaro about
sending the patches upstream.

Having this basic support in distros, as well as multicast DNS and other needed
things for Zeroconf, is a good first step, I guess, for having this support in
GNOME. Now, I just need a bit of time to start seriously adding all this to
