Yes, it can certainly be done. I have done it for http://www.yunnanexplorer.com/map/, see a good zoomed-in example here:View of Central Kunming<%20http://www.yunnanexplorer.com/map/?map_x=11432132.150567&map_y=2882521.5505753&map_zoom=15&map_visibility_Google%20Satellite=true&map_opacity_Google%20Satellite=1&map_visibility_Google%20Roads=false&map_opacity_Google%20Roads=1&map_visibility_Google%20Physical=false&map_opacity_Google%20Physical=1&map_visibility_SRTM%20Color%20Relief=false&map_opacity_SRTM%20Color%20Relief=1&map_visibility_Minority%20Groups=false&map_opacity_Minority%20Groups=1&map_visibility_Nature%20Reserves=false&map_opacity_Nature%20Reserves=1&map_visibility_OpenStreetMap%3A%20Chinese=true&map_opacity_OpenStreetMap%3A%20Chinese=1&map_visibility_OpenStreetMap%3A%20English=false&map_opacity_OpenStreetMap%3A%20English=1&map_visibility_Rivers%20%26%20Watersheds=false&map_opacity_Rivers%20%26%20Watersheds=1&map_visibility_Political%20Boundaries=true&map_opacity_Political%20Boundaries=1>
What do you need to do: 1.) set background colour in stylesheet to transparent: <Map bgcolor="transparent" srs="&srs900913;"> 2.) Then you need to change the output format to png256 in generate_tiles.py im.save(tile_uri, 'png256') I think that is actually it, but remember that some browsers do not support transparency well.
