I'll try to answer both questions as best I can. Pilot wave was replaced as a term by quantum potential and active information. Both are or contain information, and at various times are referred to as waves. They are not local nor temporal. In other words the quantum of potential of any particle, field or system is anywhere and everywhere and at all times at once. This resolves the entanglement issue. So, it has no speed because of its everywhere all the time existence. Another word for it is the holomovement, althought it could be seen that the quantum potential arises out of the holomovement which is the implicate order. The quantum potential has information on all possible properties of the particle or field, but only one option out of an unlimited number is selected and that option is the active information. Any particle/field with properties is defined or controlled by the active information. The best analogy they provide is how an autopilot of a massive ship scans the environment through radar and sends a miniscule signal to control a ship which respresents massively greater mass and energy than the signal controlling it.

Is it ontological? I think that is the major point of the Bohm-Hiley idea, that this implicate order, expressed into a explicate order by quantum potential and active information is very real, the most real and fundamental thing there is.
