I see you put him on Cc. So, Jon, please speak up if there are any issues.
One thing I forgot to mention in my blog post: OSMCoastline doesn't simplify
the coastline. In the long run Christophs tool does a better job, in the
short run you can either keep using whatever creates the shoreline 300 file,
or just don't do it. I don't really see the need for the simplification
from a performance perspective. (Low-zoom tiles are not rendered that often and
there are so few of them that it doesn't matter if it takes a little bit
longer.) And for a better looking coastline in low zoom levels you need
to do more than just line simplification.
