This was a little mesh smoothing plugin. There is now a deformer version avaiable in addition to the dialog. Just put the deformer under a polygon object to make it smooth. It supports restriction and weighting by vertex maps and it also supports the falloffs that were introduced with Mograph. It can be quite usefull for CA to reduce unwanted deformation artifacts from bones.
