Good article. Quantum entanglement is a hot field.
Einstein's model concerned the apparent speed of propagation of electromagnetic phenomena--photons. He threw in gravity effects for reasons known only to him. If you are talking about electric and magnetic fields, they propagate at a natural speed which is c in a vacuum. Einstein also gave photons a certain amount of validity. Photons are still debateable as to whether there is any such particle. Point is, if you are using E-M effects to transmit information, the natural speed is c, but you can generate other speeds using phase shift propagation. If some other fields besides electromagnetic fields are used, speeds might be different. Not enough data as yet.
