One thought is to collaborate with the mapstraction guys to come up with 
a better abstraction because I would think that they would value 
bringing all the ka-map applications under their wings also.

Another idea would be to have users classify, as best they can, their 
maps or layers to the vector, satellite and hybrid model, maybe using 
metadata. I haven't looked at how they are using that feature internally 
within the api, other than to do that obvious.
