You can of course blur the whole picture or parts of it like with focal
blur, but to selectively blur the shadowlines would be quite impossible
and also would not look realistic, because the structures of objects and
textures should not be blurred.  

It's part of the concept of raytracing that these things are quite slow,
using some kind of reflection maps like done in scanline renderers could
speed up reflection blur, but that would not be an all purpose solution.
