Richard,

I read somewhere that entanglement doesn't really qualify as transfer of information as the effect can't really be used for that purpose. If I'm not mistaken, the problem is that the "receiver" of the information cannot measure the spin of the entangled particle without changing it. Entanglement-based communication would be like a telephone line which works perfectly as long as no one is listening.

I suppose it's hard to reach agreement on stuff like that.
