I've been discussing this earlier this morning and figured that
you can probably get this done pretty easily with PostGIS 2.0,
by adding a topology-aware ST_Simplify version so and avoid
creating persistent simplified topology schemas.

Incidentally, most of the 2.0 topology work was funded by the Italian
Tuscany Region, and there are actually an handful of other public
institutions among the so called "corporate sponsors". It's just a shame
not to see the JRC in there...
