Yes, interesting software. That would mean to render on the fly. I am not sure if my weak virtual server would cope with the task doing both at the same time, rendering tiles and serving tiles.

I will look into this, thanks!
Meanwhile, I'm thinking about aging the tiles using the means of the operating system. Thus, the rendering process could pick all the old tile image files at night and start their rerendering. At the moment, I am not completely sure which way to go but I will post the result as soon as I have a solution.
