We could provide caching using [wiki:BluePrintGISTileCache TileCache] - for both performance & the ability to work offline
 * [wiki:GIS/InstallationGuidelines/Linux#ProxyCache MapProxy] also allows reprojection to different SRS

From a user perspective this just includes Remote WMS layers.

(Local WMS Layers would be seen as [wiki:BluePrint/GIS/ShapefileLayers Shapefile Layers] or [wiki:BluePrintGISImageLayers Image Layers])

 * A single one for the server - not 1/layer!?
