[Twisted-Python] Is multicast supported on windows platform?

Hi everyone! I am just starting to learn Twisted. My first attempt is to write a small client app that will join to a multicast group and then read the receive stream. The code would have to run on Windows and *nix. As I'm reading the docs and browsing the code I stumbled across the twisted.internet.udp MulticastMixin docstring that states: class MulticastMixin: """Implement multicast functionality. Initial implementation, probably needs some changes for Windows support. """ My first question therefore: "is multicast supported under Windows?" Thanks for any help. Pierre
