My only use of Avahi thus far has been in anger when confronted with
various Ubuntu Linux machines that have decided "the network/NIC/DHCP
server/dog has gone away" and instead of talking to the (all the while
perfectly functional) DHCP server insisted on using a 169.254.x.x IP
address until I removed all traces of anything Avahi from the system and
"ifup eth0" started working again.

So, as you can see I'm not exactly in favour of the technology :-/

Maybe in another few years when the implementations are mature enough...
but even then it all feels slightly too "automagical" for my taste.
