  Measuring velocities requires the synchronization of spatially-separated
clocks. Because this synchronization must precede the determination of
velocities, no system of clock synchronization--such as that based on
Einstein's presumption of light-speed isotropy--can ever be founded on an
experimentally-validated velocity. I argue that this very old observation,
which lingers in the philosophical literature under the heading
``Conventionality of Synchronization,'' suggests an explanation of why
``spooky'' quantum correlations can transfer no information at any speed,
superluminal or otherwise. This work constitutes the first application of the
Conventionality doctrine outside of Relativity itself.
