If you're smart enough to actually do multicast, you're smart enough to remove the filter for 224/3. If you're not smart enough to remove the filter, or you're smart enough but you're one of the 95% that doesn't do multicast, your site should be doing bidirectional filtering of 224/3. ;) (Do you really want your users emitting outbound packets to/from 224/3 if you don't actually do multicast? Probably not...)
