I don't know why it is generally enabled on "server" installations. That being said, the only time I've had a legit use of it was on a media server, running mediatomb, which uses avahi to do SSDP/mDNS/zeroconf/DNS-SD [1], and on the client running VLC (I think the "local network" options interface with avahi itself). Which actually ended up being quite nice. I usually disable it, and try to uninstall it completely, on other server installations.
