What can you tell us about your map API? it looks custom-rolled from the end-user perspective.

It was all written for SkyVector. None of the other mapping API's could handle Lambert Conformal Conic projections.

I assume it's proprietary then? Do you have any plans to license it? Open source non-business critical portions?

We are very unlikely to license the code to just anybody, but we are definitely exploring allowing 3rd party sites to embed an interactive (non-static) chart viewer. We've got a few concerns, however. First, we don't want to do it for free. Some sort of on-map advertising would probably accompany it. Second, we don't want to enable our competition. Our maps are what set us apart in the very competitive aeronautical information space. Giving away our advantage would be shooting ourselves in the foot.
