Migrate ALL of SimpleGEO's services

Funnily enough at SpacialDB we had a very similar API to SimpleGEO, namely the idea of Layers. Each dataset in SpacialDB maps to a layer, accessible as GeoJSON via a REST API. We decided to build SpacialDB on PostgreSQL so we could handle more than just simple points. Our API can store complex geometries (2D/3D polygons, line, multipolygons and multilines). This means that in addition to migrating your Storage data from SimpleGEO to SpacialDB you could also replicate SimpleGEO's Features, Context and Places API's with SpacialDB. At least the parts that are under creative commons.
