Hi,

Take a look at the GEOS library (http://trac.osgeo.org/geos/), MapServer
can be built with GEOS support, and then you could use your favourite
mapscript flavour to run commands such as 'simplify'. for example see
http://www.mapserver.org/mapscript/php/index.html?highlight=simplify

For speed issues, most of the time I will post-process the data in
something like PostGIS or GRASS beforehand.
