Here you don't need to specify the version, I think you can describe like this: "Pure-Python interface to Apple Bonjour"

Same here, I would replace this line using this text:

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.
