Hi Carl, You can try hacking around with the QGeoMapOverlay stuff yourself, but it could be a little painful.
We only really have partial overlay support, but we still need to flesh out that part of the API before it's really easily usable. We're doing this in order to enable the use of traffic tiles from the Nokia servers for use with the Nokia plugin. http://bugreports.qt.nokia.com/browse/QTMOBILITY-702 The goal is let plugins report the names of overlays they support, let the users specify the enabling / ordering of the layers, and to reuse the getTileImage() method in the plugin (by adding an optional overlay name to the request object) so that it's simple to extend. If we can integrate this into the tile fetching and rendering part of the tiled map helpers it'll mean less pain for dealing with overlays where they're tied to a particular plugin. Overlays which aren't tied to a particular plugin will get more interesting. I'd prefer to wait until a little later before I commit to adding more stuff to help with the non-plugin-specific overlays, since we have some changes which are closer to the front of the queue which will cause some large ripples through the codebase.
