Hi,
Sorry for the late reply, I overlooked you email.

To remove the mapnikrenderer plugin from the plugin list you have to:
 - remove -lmapnik from the preprocessor.pro in the preprocessor subdirectory
 - remove the line Q_IMPORT_PLUGIN( mapnikrenderer ); from the
main.cpp in the preprocessor subdirectory
 - remove the mapnikrenderer plugin from the preprocessor_plugins.pro

If you are interested in bringing part of those project to MoNav as a
rendering plugin you are more than welcome. As a matter of fact I am
more interested in developing new routing / address lookup techniques
than rendering plugins.

Each city has its own street name data structure. This means the
average size of these street name data structures is about 0.7KK per
city in Germany.
