What would be really useful is if you could describe a hypthetical interface by which you would get whatever information you want to get. Write a little program assuming that the interface works however you like and show it to me. My problem is that I'm far too close to the forest so to speak: When I think about what interfaces could be provided I just get overwhelmed by the options. Give me an idea of an api that you would like to work with and I have something concrete to aim for.
