This is good to see Jon.

@All how can we make this happen within OSGeo?

We’re building in library support for a few languages (e.g. Javascript, Python) and some tools (e.g. Leaflet and NASA’s Web World Wind).

JSON gzips very well on the wire, which helps a lot with transfer speed and our tests indicate that it’s typically not very much worse than a compressed binary format. We’ve worked successfully with rasters of millions of pixels in size.
