The Spybot hardware itself appears capable of simple proximity detection.
Looking at outputs from the IR detector modules on an oscilloscope, I can see
the Spybot's own pings. This includes the absence/presence of range sensing/ID
bits due to reflections (or lack of reflections) from nearby objects.
It seems like the key is if the ROM would include it's own received information
in the World Relation table (or if there was another way to obtain this info).
Does anyone know if it can, or a method to obtain the info? This seems like
such an obvious "feature" that Lego would have included it in the ROM
*somewhere*... (any Lego folks out there with a hint?).
There is always the possibility that the ROM throws out, ignores, or by design
is not capable of receiving messages while transmitting. If any of these are
the case, we're out of luck.

This much I know: the Spybot can do proximity detection if what it is detecting is a well-defined IR-emitting object such as a Spybot controller or (...)
