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

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