The trouble is that even in the same 10m diameter room, close enough will stop
working under certain conditions, some of the time. The signal measured
by the radio can vary through:
2. angle of antennae relative to the other antennae,
5. noise from other radio sources (including laptops in the same room
that may have missed a beacon).

I've not tested that scenario. Interesting possibility.

XO-1 explicitly or spontaneously creates, based on icon trigger in
