"DNS Service Discovery (DNS-SD) is a component of Zeroconf
networking, which allows servers and clients on an IP network to
exchange their location and access details around the LAN without
requiring any central configuration.
"Most Linux distributions supply the Avahi library for Zeroconf
support, but not nearly as many users take advantage of it. Let's
look at an easy-to-set-up use for DNS-SD: providing automatic
bookmarks to services. All it takes is an Apache module and a
Firefox extension."
