Agreed; having something like this tied to your GPS would be a great service. It would also be useful to quickly know the time the spot becomes illegal again.

I can imagine, too, this would be incredibly useful if self-driving cars ever become a reality (or in helping them become a reality). After one drops you off at the show downtown, it could then check for nearby parking. But maybe this is dreaming too far down the road...
