Hey, MapD author here (Todd Mostak). I'm working on a release now - hopefully it will be out by the end of the year! Would really appreciate help from anyone interested in the project - todd@map-d.com
As a side note, I was excited to see that there was some geospatial support in there. That's certainly piqued my interest! How much of a focus was spatial support?
Todd - Would love to help you out. I will send you my email.
That sounds really interesting. I will send you an email.
