2005 As a last resort w.r.t. routing, a packet is sent to all
hopCount=1 nodes in the peer list. The idea is "we dunnow what
to do with it, let's pass it on to our neighbours". The peers
will go through the same three stages, so sooner or later
someone is bound to find a way to get to the addressed node.
Note that broadcasting really is a method of last resort.
However, the idea is that if the node is finally reached (at a
very high cost to the network), it will have an ant route back
to the originating node a response packet can now follow. When
the response packet arrives, the ant route has been built up in
the opposite direction as well (think about it). So broadcasting
is typically necessary only when two distant peers need to setup
communication, after that ant routing kicks in and the network
will hopefully self-select the most efficient path.
