Thanks for confirming.

This shouldn't be a big surprise. It's very platform specific as to 
whether you can bind to a multicast address or not. From the previous 
mails then I think the only reason you were doing this on Linux is 
because IP_MULTICAST_ALL doesn't work with IPv6 sockets and you are 
getting interference on systems with multiple network interfaces.
