My philosophy when writing the networking code in rat was that this is 
an operating system issue, and the media tool shouldn't attempt to 
circumvent routing policy. Configure the system to route multicast to 
an appropriate interface using "route add -net 224.0.0.0 netmask 
224.0.0.0 eth1" or similar.
