While it's an exciting thought, I don't think apple will implement that until its more reliable ("just works"). I doubt others will get a chance to implement it because it would require low level access to the wireless hardware, but I really am not qualified to comment here. I think apple probably wanted GPS but had to axe it for battery life and/or form factor (both spec's probably sitting at hard requirements from the early stages of the phone's design). So then I'd expect GPS to be on future models.
