Ditto on the quantum level. When the particles are entangled, it simply means that learning one tells you something about the other... but influence spread is still limited to the speed of light.
On the quantum level, it doesn't mean that opening one envelope tells you about the contents of the other envelope, it actually determines it. Up until the point of observation, each coin half is in a superposition of being both a head and a tail. In the classical model, one envelope has a head, and the other has a tail, you just don't know which is which yet.

That IS spooky.
