Nice work on the script!

Would it be simpler to add the polygon simplification into the polygon 
loader in osmosis itself?  Already being java it might be simpler than 
rewriting in perl.  There is a single class named PolygonFileReader 
which parses a polygon file into a java.awt.geom.Area instance.  It has 
a method named loadSectionPolygon which reads a single polygon from the 
file and converts into an Area class which is subsequently added to or 
subtracted from the result Area.  Presumably this loadSectionPolygon 
method could be modified to call a "simplification" method that accepts 
a complex set of coordinates and returns a simplified set of coordinates.

Would this be hard to do?

I'm not volunteering to do it just yet but if it sounds straightforward 
I can add it to the future features list ...
