To render one tile doesn't take long at all. To render all tiles for 
area size of Oxford (zoom levels 1- 17) is about 10-20 min on my laptop. 
It is possible to set up tile cache which is populated automatically by  
user requests.

I'll write 'HOWTO' and publish all scripts over this weekend hopefully. 
Good place to start is to build Mapnik and play with python demo 
($(mapnik_source)/demo/python/rundemo.py).

Thanks
Artem.
