mdnsd - embeddable Multicast DNS Daemon

"mdnsd" is a very lightweight, simple, portable, and easy to integrate open source implementation of Multicast DNS (part of Zeroconf, also called Rendezvous by Apple) for developers. It supports both acting as a Query and a Responder, allowing any software to participate fully on the .localnetwork just by including a few files and calling a few functions.  All of the complexity of handling the Multicast DNS retransmit timing, duplicate suppression, probing, conflict detection, and other facets of the DNS protocol is hidden behind a very simple and very easy to use interface, described in the header file. The single small c source file has almost no dependencies, and is portable to almost any embedded platform. Multiple example applications and usages are included in the download, including a simple persistent query browser and a tool to advertise .local web sites.

The code is licensed under both the GPL and BSD licenses, for use in any free software or commercial application. If there is a licensing need not covered by either of those, alternative licensing is available upon request.

Author's Note
My only reason for putting the (far more than anticipated) time into this project was in the hope that it would be useful for others and help encourage wider support for Zeroconf/Rendezvous.  If this is helpful in an integration project, or if I can help further in such an effort, just let me know.
