It seems appropriate that this followup should be cross-posted also;
my apologies to anyone this offends.

As an addendum to Mr Seeger's excellent list of references on the issue
of non-local interactions in quantum mechanics, here are two papers that
do indeed claim the effect can be used to transmit information faster
than light:

	N Herbert: Foundations of Physics vol 12 p 1171 (1982)
	[see also Herbert: Quantum Reality - Beyond the New Physics]

	Summary: Two correlated particles are prepared and allowed to
	separate.  One is subjected to a measurement against a basis
	set; it is supposed that the other will then be in an eigenstate
	of that same basis set.  Information is transferred by choosing
	one basis set or another; it is asserted that the receiver can
	detect which basis set is used (even though the specific eigenstate
	itself gives no information)

	A Datta, D Home, A Raychaudhuri: Physics Letters A vol 123 p 4 (1987)

	Summary: Two particles are prepared by a decay method that violates
	CP invariance.  The resulting wave functions exhibit a weak
	interaction term whose eigenstates are nonorthogonal.  It is
	asserted that a measurement that casts one particle into a given
	eigenstate therefore has an effect on the observed statistical
	distribution of the eigenstates of the other.
