Paul, there are two issues here as I see it:
 
1). Does one obtain the correct quantum correlations by using the singlet
wave function before either particle is detected? For the spin-half case
I get < (S1.a) (S2.b) > = -(hbar^2) a.b / 4 for arbitary unit vectors
a and b, particles 1 and 2 in the (pre-detection) singlet state. Is this
the correct answer or no?
 
2). Are the predictions of QM inconsistent with the assertion that the
setting of the near polarizer *never* influences the outcome of the
distant measurement? If this is what Eberhard claims to prove then I
will read his derivation as soon as I can find the time.
 
I suspect, rather, that the most can say for certain is that if QM is
correct, the polarization states of the photons are incompletely
determined until the measurements are made (a statement with which
Bohr would have agreed decades ago), and that the correlations
predicted by QM between distant measurements would *otherwise*
imply such an influence.
