	I suspect what seeger@beach.cis.ufl.edu was referring to is ?Bells?
theorem, which says that there can be instantaneous effects at a distance, but
because of the way they work you can't transmit information with them.  You
can send data from the sender that allows you to interpret the data at the
receiving end, but that data moves at or slower than light, so the information
still only travels at lightspeed.

	Summary: Yes, apparently there can be instantaneous effects at a
distance, but you can't use them for anything.
