pybonjour provides a pure Python interface (via ctypes) to Apple Bonjour and compatible DNS-SD libraries (such as Avahi). It allows Python scripts to take advantage of Zero Configuration Networking (Zeroconf) to register, discover, and resolve services on both local and wide-area networks. Since pybonjour is implemented in pure Python, scripts that use it can easily be ported to Mac OS X, Windows, Linux, and other systems that run Bonjour.
