Hi, openwebgis!
Nice project! Good luck with it!
However, I should mention that you project is not exactly "open" and "free". Yes, it is free from advertisements, but you do not provide source code or even compiled installer (like Geoserver or Mapserver, which ARE free and open-source). Your project simply falls within definition of "free web service" just like those of Google maps or Yandex maps. Please, be understandable of that.
Regards!
