I am "getting to know" Leaflet + TileStache, and wondering if there is a way to not have GeoJSON tile layers go back to the server on every single zoom level, but rather fetch every, say, 3 zoom levels ... and instead do client-side clipping and zoom-level specific styling (like start rendering labels, etc). of features it already has loaded.
This would save a lot of traffic....
I see a similar question came up a while back:
but never seems to have been definitively resolved.
