To be useful for our mesh tests this "virtual air" would have to allow
us to create 3 groups, each one a superset of the previous. The
smallest group would be the set of nodes that can a node communicate
with ("A can talk to B"). The next larger group would be nodes on
which a node that can interfere ("A can screw up C's reception").
Finally, the largest would be nodes that can detect each other ("A can
detect when D is transmitting").
