Page 44 of "Applied Cryptography" discusses a point to point *public*
key exchange protocol called the "Interlock Protocol" (invented by
Ron Rivest and Adi Shamir). This protocol is an attempt to foil the
man-in-the-middle attack. The protocol does not provide a %100
guarantee against man-in-middle, but it does make it much harder (or
so says the book).
Perhaps Robert's device really uses a variation of the Interlock
Protocol, and not Diffie-Hellman (mentioned only as a red herring?).
