I already told Robert this.  Perhaps I wasn't sufficiently eloquent to
get my point across.  But let me just say that I agree completely with
Benjamin Weiner's point.  It makes perfect sense to argue about what can
or cannot happen according to orthodox QM without doing any experiments.
If Sarfatti claimed he had a NEW THEORY that contradicted orthodox QM
one would have to see if his theory was consistent and met experimental
tests.  But he seems to be claiming that orthodox QM predicts FTL
communication.  Of course, his way of doing orthodox QM looks very
unorthodox, i.e., wrong.
