only if your local receiver is seeing it's packets on the wire.

something really weird is going on your host -- it's not seeing it's 
own multicast packets being put out on the wire.  I don't know how 
well that should work with all platforms, but on the solaris and 
macos machines I run beacons on they usually see things just fine.

it means never seen data. so those other receivers have never seen your sender
