So, what precisely is the measurement protocol he is using to make wave
or particle like measurements on the particles constituting each beam?
Has anyone got a link, because the article doesn't say, and googling
failed to find anything? If we knew that, we could write down the sort
of statistics we would expect from a succesful 'bilking' experiment,
and perhaps that would considerably elucidate the situation (most
likely by proving that bilking is actually undetectable).
Only this one

As far as I remember (?) you need few photons (something
like 50 or less) to realize if it is a diffraction
pattern or an interferential one. But you also need
a very clean source of entangled photons imo.
There is an interesting paper here
http://www.arxiv.org/abs/quant-ph/0506027
about that 'bilking' or, to say it better,
once the future has unfolded, it cannot change
the past.

"In the early 1950s, my mentor Fritz Bopp
pondered the question as to why the probabilities
in quantum mechanics appear as absolute squares
of complex amplitudes. This led to a series
of papers with titles such as "Dice Games Whose
Tokens Move Quantum Mechanically". In 1953, I had
the great chance to spend a year in Copenhagen.
One day Niels Bohr came to me saying: "I received
again a manuscript by Professor Bopp. I do not
understand why people occupy themselves with
questions which have been clarified for decades
while there are so many unsolved interesting new
problems around." My imprudent answer: "Maybe things
are not so clear", prompted a series of discussions."
