ok... broadcast was bad choice of word. I meant, when a edge node
register to supernode what happens next? My guess was that supernode
"tells" everyone about the new edge, is this correct?
Now about the broadcast... when a node send a ARP who-has, who replies
to sender? the edge node who has the awnser or the supernode awnser,
since he knows who has?

of course.. this is why i´m trying to understand the design :-)
