This looks really interesting. It might be a viable replacement for the back-end of an app I am working on that provides navigation for visually impaired people through spacialized sound. https://github.com/soundscape-community/soundscape

The back-end is currently based on a postgis database and a python app serving geojson tiles at zoom level 16. It currently runs on a single Hetzner server due to the resource requirements of imposm which is used to import the data into the database. Reducing hosting costs would really help us to insure the long term sustainability of the app.

I don't know yet how different the schema is and how easy it will be to support.

Soundscape was originally a Microsoft research project but they open sourced it when they shut down the app last year.
