that matrix cannot create asymmetric paths (at least, not unless you are also 
tinkering with power settings on the nodes), and will have trouble making hidden 
transmitters (station A can hear station B and C but B and C cannot tell the 
other exists) as a node can hear that something is transmitting at much lower 
power levels than it cn decode the signal.
