sorry guys but all these "wishes, issues" belongs to vector library I use ... http://code.google.com/p/mapsforge/
thanks for the pointer. I checked the 'issues' page there and it looks like the wish has already been granted, they are implementing something like MapCSS now:
"Add an API to modify the rendering style at runtime"http://code.google.com/p/mapsforge/issu ... 20Modified
Basically, there is an XML file that can be edited, which is similar to osmarender stylesheets.
Could you, please, look into this? I fyou do not have the time, or if this is too low on your priority list, I could give it a try, however, I do not know mapsforge well, so I do not know if I can find my way around.
