-Apple's mDNS Responder (part of "rendezvous" technology)
+The mDNSResponder project is a component of Bonjour,
+Apple's ease-of-use IP networking initiative:
+<http://developer.apple.com/bonjour/>
+
+Apple's Bonjour software derives from the ongoing standardization
+work of the IETF Zero Configuration Networking Working Group:
+<http://zeroconf.org/>
+
+The Zeroconf Working Group has identified three requirements for Zero
+Configuration Networking:
+1. An IP address (even when there is no DHCP server to assign one)
+2. Name-to-address translation (even when there is no DNS server)
+3. Discovery of Services on the network (again, without infrastucture)
+
+Requirement 1 is met by self-assigned link-local addresses, as
+described in "Dynamic Configuration of IPv4 Link-Local Addresses"
+<http://files.zeroconf.org/draft-ietf-zeroconf-ipv4-linklocal.txt>
+
+Requirement 2 is met by sending DNS-like queries via Multicast (mDNS).
+
+Requirement 3 is met by DNS Service Dicsovery (DNS-SD).
+
+Self-assigned link-local address capability has been available since
+1998, when it first appeared in Windows '98 and in Mac OS 8.5.
+Implementations for other platforms also exist.
+
+The mDNSResponder project allows us to meet requirements 2 and 3.
+It provides the ability for the user to identify hosts using names
+instead of dotted-decimal IP addresses, even if the user doesn't have a
+conventional DNS server set up. It also provides the ability for the
+user to discover what services are being advertised on the network,
+without having to know about them in advance, or configure the machines.
