To open the question up - what are the example or best case interfaces and mechanisms of a "spatially-enabled cloud database"?
And by "cloud" I mean internet accessible, on-demand, fast provisioned, near-limitless scaling without me having to do the administration. So setting up PostGIS/JTS/CouchDB are not cloud databases, just db's that people tend to run on horizontally scaling systems. As a first step, I'd like to see a GeoJSON API for a schema-less 'cloud' datastore that exposed an OpenSearch-Geo interface for querying it. Start with Point, but definitely needs to gain support more complex features as well. The store should be agnostic to the language I write my application in.
