You're most welcome to do that, as in #osm-nl we have talked about 
regionalised rendering as well, in the past. I've rolled one small 
aspect of this out on our walking routes map, which renders different 
shields for The Netherlands and Belgium. I did copy our country boundary 
polygons to another table, because if for some reason the country 
boundary in OSM is non-closed, the whole regionalised rendering would 
fall over.

My thoughts are that the import process should sort out the hard part of 
this: comparing of features against a polygon, and stamping them with a 
field we can filter on in mapnik. Either by running some sql at the end 
of the import (but should also work for diffs and changed polygons), or 
by doing this itself.

What were the other issues you had thought up?
